Like the pin configuration of microprocessor, the microprocessor also contains 40 pins dual in line. However, unlike the microprocessor, an to have better performance, operates in 2 modes that are minimum and maximum mode. The minimum mode is a single processor configuration while the maximum mode is a multiple processor configuration. Due to this reason, in the 40 pin IC of microprocessor, 8 pins i. We will discuss the pin description in this section.

But before that have a look at the pin diagram of microprocessor. An microprocessor is also a 40 pin IC but has few separate pin configuration for minimum and maximum mode which we will discuss in this article. Here, from the above figure it is clear that from pin number 24 to 32, we have shown the different configuration for minimum and maximum mode. However, excluding these 8 pins, the rest 32 pins are the same for both minimum as well as maximum mode.

So, let us move further to understand the operation of each pin in the pin configuration of V SS — Pin number 1 and 20 — These two pins acts as the ground. This pin directs the extra current of the microprocessor to ground. We know that the microprocessor has bit address bus and bit data bus. So, the 16 lines of the address and data bus are multiplexed together so as to reduce the number of lines inside the IC.

We are aware of the fact that at a time either address or data will be transmitted by the bus. So, at a particular time only either the address or the data bus will be enabled from the multiplexed buses. In the case of memory operations, these pins act as an address bus and contain the memory address of any particular instruction or data.

Basically, the signal at S 3 and S 4 show that which segment is currently accessed by the microprocessor among the four segments present in it.

The table below will show the encoding of S 3 and S 4 :. Also, S 5when enabled, shows the presence of an interrupts in the microprocessor. So, basically, it serves as an interrupt flag.

The signal at S 6 shows the status of the bus master for the current operation. More simply we can say, whether the is the bus master or any other proficient device is acting as the bus master.

When 0 is present as the signal at this pin then it indicates the is holding the access of the bus otherwise it is high i.Maximum current draw is 50mA. Arduino Uno is a microcontroller board based on 8-bit ATmegaP microcontroller. Along with ATmegaP, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc.

Each pin operate at 5V and can provide or receive a maximum of 40mA current, and has an internal pull-up resistor of KOhms which are disconnected by default. Out of these 14 pins, some pins have specific functions as listed below:.

Along with 14 Digital pins, there are 6 analog input pins, each of which provide 10 bits of resolution, i. They measure from 0 to 5 volts but this limit can be increased by using AREF pin with analog Reference function. Arduino can be used to communicate with a computer, another Arduino board or other microcontrollers. An ATmega16U2 on the board channels this serial communication over USB and appears as a virtual com port to software on the computer.

However, on Windows, a. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board.

A SoftwareSerial library allows for serial communication on any of the Uno's digital pins. The Arduino software includes a Wire library to simplify use of the I2C bus.

When ATmega chip is used in place of Arduino Uno, or vice versa, the image below shows the pin mapping between the two.

This clock is powered with unbroken battery even that the device is turned OFF. This article is meant to give a little insight regarding RTC DS real time clock interfacing with microcontroller.

This article can walk you through the steps concerned in interfacing RTC DS with a microcontroller. There are different types of RTC real time clock devices are available in the embedded system market and these are classified into different types like supply voltage, package type and pin diagram etc.

A few kinds of RTC devices are. Based on the crystal frequency, the RTC device offers years, months, weeks, days, hours, minutes and seconds. Here, RAM memory is used to store the data and battery is for backup in case of power supply failure. The I2C bus protocol lets many dependent devices at a time. Every dependent device must comprise of own address to denote on it. The master device interconnects with a particular dependent device by an address. RTC registers are placed at 00h to 0Fh locations.

RAM memory registers are also located at 08h to 3Fh locations. These registers are used to run calendar functionality and time of the day and displays the weekends.

RTC DS comprises of two extra registers like control or status register1 and control or status register2. These wires are used to transfer data between devices which are connected to the bus. So, we have connected externally via a serial communication for confirming the comprising data. I2C bus is used in the interfacing of RTC with a microcontroller. So, the data transfer is in the form of packets or bytes, and these are followed by a credit. In transmitting mode, after selecting a slave device by using address bit, the master device releases the start condition.

The address bit includes seven bits, that specify the slave devices as DS address. Control Status Register Address: This register address is mainly used to let the control status registers. In addition to this, data frames also discussed which are used to transfer and receive the data with an appropriate program.

In these situations, DMA can save processing time and is a more efficient way to move data from the computer's memory to other devices. In order for devices to use direct memory access, they must be assigned to a DMA channel.

tm4c123gh6pm pin diagram

Each type of port on a computer has a set of DMA channels that can be assigned to each connected device. In this mode current address register of channel 0 is used to point the source address and the current address register of channel is used to point the destination address in the first transfer cycle, data byte from the source address is loaded in the temporary register of the DMA controller and in the next transfer cycle the data from the temporary register is stored in the memory pointed by destination address.

After each data transfer current address registers are decremented or incremented according to current settings. The channel 1 current word count register is also decremented by 1 after each data transfer. Auto initialize In this mode, during the initialization the base address and word count registers are loaded simultaneously with the current address and word count registers by the microprocessor.

The address and the count in the base registers remain unchanged throughout the DMA service. After the first block transfer i. Transferring data between system memory and an device requires two steps. Data goes from the sending device to the DMA controller and then to the receiving device.

The microprocessor gives the DMA controller the location, destination, and amount of data that is to be transferred. Then the DMA controller transfers the data, allowing the microprocessor to continue with other processing tasks. When a device needs to use the Micro Channel bus to send or receive data, it competes with all the other devices that are trying to gain control of the bus. This process is known as arbitration. It is the DMA controller, however, that takes control of the bus when the central arbitration control point grants the DMA slave's request.

Watford were in the game for a brief spell against United last time out but to be fair it could and probably should have 4-0 or 5-0 before the Hornets won their penalty.

They head to north London with all of their top boys available now and they will be looking forward to the game. The only thing standing in the way of City and a comprehensive win here is City themselves.

And that makes this the banker game of the season. Spurs, meanwhile, missed three sitters. On paper Spurs win this game easily but if Watford are to have a chance Richarlison will be the main threat.
