1.7.1
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.
