GPFDAT
Bit
Description
GPF[15:0]
[15:0]
When the port is configured as input port, the corresponding bit is the pin state.
When the port is configured as output port, the pin state is the same as the
corresponding bit. When the port is configured as functional pin, the undefined
value will be read.
