1.6.11
The OLAT register provides access to the output
latches. A read from this register results in a read of the
OLAT and not the port itself. A write to this register
modifies the output latches that modify the pins
configured as outputs.
REGISTER 1-11:

bit 7-0
OUTPUT LATCH REGISTER (OLAT)
OLAT – OUTPUT LATCH REGISTER 0 (ADDR 0x0A)
OL7:OL0: These bits reflect the logic level on the output latch <7:0>.
1 = Logic-high.
0 = Logic-low.
