WebJun 20, 2012 · Initially the first display is activated by making P3.0 high and then digit drive pattern for “1” is loaded to the Port 1. This will make the first display to show “1”. In the mean time P3.1 will be low and so do the second display will be OFF. This condition is maintained for around 1ms and then P3.0 is made low. Now both displays will be OFF. WebJul 3, 2024 · When we use Port 0 as an input port, the internal latch should know that it’s being used for input, and thus, a digital 1 (FFH) is written at the port address of 80H. This turns off the transistors causing the pin to float in high impedance state connecting it to the input buffer. We can read data from ‘Read Pin Data’/’Read Latch Bit.’
