GPOUT1
Meaning:
General Purpose Output Pin 1.
Location:
IOPINS.1
Set:
The CPU sets this bit to set the GPOUT1 pin high (referenced toV
L
). The CPU
can also read this bit. Reading the bit indicates the state of the output flipflop
before the output buffer. Therefore if the output pin is driving a large load (e.g. an
LED) that compromises the logic level, the CPU can still read the correct logic
state of the output pin.
Clear:
The CPU clears this bit to set the GPOUT1 pin state to 0.
