20.8.4 GPIO INPUT REGISTERS
The GPIO Input Registers can always be used to read the state of a pin, even when the pin is in an output mode and/or
when a signal function other than the GPIO signal function is selected; i.e., the Pin Control Register Mux Control bits
are not equal to ‘00.’
The MSbit of the Input GPIO registers have been implemented as a read/write scratch pad bit to support processor spe-
cific instructions.
Note: Bits associated with GPIOs that are not implemented are shown as Reserved.
