configuration register (ADPC) and in the input mode by using PM2. Use these pins starting from the upper bit.
Port 2 is an 8-bit I/O port with an output latch. Port 2 can be set to the input mode or output mode in 1-bit units
This port can also be used for A/D converter analog input.
To use P20/ANI0 to P27/ANI7 as digital input pins, set them in the digital I/O mode by using the A/D port
To use P20/ANI0 to P27/ANI7 as digital output pins, set them in the digital I/O mode by using ADPC and in the
To use P20/ANI0 to P27/ANI7 as analog input pins, set them in the analog input mode by using the A/D port
All P20/ANI0 to P27/ANI7 are set in the digital input mode when the reset signal is generated.
Figure 4-12 shows a block diagram of port 2.
