1.6.2
INPUT POLARITY REGISTER
This 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
R/W-0
IP7
IP6
IP5
IP4
IP3
IP2
IP1
IP0
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
IP7:IP0: Controls 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
