Input/Output Ports
7.17 Port G (PG0 through PG7)
The port G is a general-purpose, 8-bit input/output port. For this port, inputs and outputs can be specified in
units of bits by using the control register PGCR and the function register PGFC1. A reset allows all bits of the
output latch PG to set to "1," all bits of PGCR and PGFC1 to be cleared to "0," and the port G to be put in input
mode.
Input is disabled right after reset. To enable input, set the corresponding bit of PGIE to “1”.
Besides the input/output port function, the port G performs the key-on wake-up input function.
