OUTPUT LATCH REGISTER (OLAT)
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:
OLAT – OUTPUT LATCH REGISTER 0 (ADDR 0x0A)
R/W-0
OL7
OL6
OL5
OL4
OL3
OL2
OL1
OL0
bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-0
OL7:OL0: These bits reflect the logic level on the output latch <7:0>
1 = Logic-high.
0 = Logic-low.
