WebEach port of 8051 has bidirectional capability. Port 0 is called 'true bidirectional port' as it floats (tristated) when configured as input. Port-1, 2, 3 are called 'quasi bidirectional port'. … WebThe pin diagram of 8051 microcontroller looks as follows − Pins 1 to 8 − These pins are known as Port 1. This port doesn’t serve any other functions. It is internally pulled up, bi-directional I/O port. Pin 9 − It is a RESET pin, which is used to reset the microcontroller to its initial values. Pins 10 to 17 − These pins are known as Port 3.
Features of Port 0 1. Address is 80H 2. Construction: Port 0 has a D-type latch, unidirectional buffer, and 2 FETs at each pin. It does not have an internal pull-up resistor. An external pull-up resistor is needed when Port 0 is defined as an output port. 3. Port 0 of the 8051 has two main functions: To be used as … See more Features of Port 1: 1. Address is 90H 2.

WebThe processor 8051 defines a few instructions to address a single bit to clear to 0, set to 1 or test the value followed by a conditional branch to bypass the following code if the bit was set or clear. These instructions are very efficient, using only 2 bytes. WebSFRs related to the I/O ports: The 8051 has four I/O ports of 8 bits, for a total of 32 I/O lines. Whether a given I/O line is high or low and the value read from the line are controlled by the SFRs. The SFRs control the operation or the configuration of some aspect of the 8051.
