I/O PORTS
PORT F CONTROL REGISTERS (GPFCON, GPFDAT, and GPFPU)
If GPF0 - GPF7 are used for wakeup signals in Power_OFF mode, the ports must be configured as external interrupt
(set in Interrupt mode).

When the port is configured as input port, data from external sources can be
read to the corresponding pin. When the port is configured as output port, data
written in this register can be sent to the corresponding pin. When the port is
configured as functional pin, undefined value will be read.
0: The pull-up function attached to to the corresponding port pin is enabled.
1: The pull-up function is disabled.
