Port 2 is an I/O port with an output latch. Port 2 can be set to the input mode or output mode in 1-bit units using port
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 configuration
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 output
All P20/ANI0 to P27/ANI7 are set in the analog input mode when the reset signal is generated.
Figure 5-12 shows a block diagram of port 2.
Caution Make the AV
PM2 to “1”, and bits 6 and 7 of P2 to “0”.
