DATA PORT REGISTERS

Two registers provide access to the two GPIO ports:

• GP0 (provides access to data port GP0)

• GP1 (provides access to data port GP1)

A read from this register provides status on pins of

these ports. A write to these registers will modify the

output latch registers (OLAT0, OLAT1) and data output.
