INPUT POLARITY (IPOL) REGISTER
The IPOL register allows the user to configure the
polarity on the corresponding GPIO port bits.
If a bit is set, the corresponding GPIO register bit will
reflect the inverted value on the pin.
REGISTER 1-2:
IPOL – INPUT POLARITY PORT REGISTER (ADDR 0x01)

IP7:IP0:
These bits control the polarity inversion of the input pins <7:0>.
1
= GPIO register bit will reflect the opposite logic state of the input pin.
0
= GPIO register bit will reflect the same logic state of the input pin.
Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
