Port 8 is I/O port with an output latch. Port 8 can be set to the input mode or output mode in 1-bit units using port
Digital Inputs to the P80 to P83 pins must be enabled or disabled in 1-bit units using port input mode register 8
This port can also be used for an input voltage on the (+) sides of comparators 0 and 1, an input voltage on the (−)
Reset signal generation sets port 8 to analog input mode.
Figures 4-20 to 4-22 show block diagrams of port 8.
