OUTPUT LATCH REGISTERS

Two registers provide access to the two port output

latches:

• OLAT0 (provides access to the output latch for

port GP0)

• OLAT1 (provides access to the output latch for

port GP1)

A read from these registers results in a read of the latch

that controls the output and not the actual port. A write

to these registers updates the output latch that controls

the output.
