7.17 Port G (PG0~PG7)
PG read
(Function control)
The port G is a general-purpose, 8-bit input/output port. For this port, outputs can be
specified in units of bits by using the control register PGCR and the function register
PGFCx. A reset allows all bits of the PG, PGCR, PGFC1 and PGFC2 to be cleared to "0,"
and the port G to be put in output disable mode.
Besides the input/output port function, the port C performs other function: PG0 through
PG2 have a serial communication function (SIO/UART ch2).
If the port G is used as UART/SIO function port, select the function with the function register
of the corresponding port and set the open drain control register along with the serial
setting register. When the function registers 1 and 2 are set as the port, please do not set
any other function.
