IOINTEN REGISTER
Unimplemented: Read as ‘0’
DDR6:DDR0: Data Direction Register* bits
1 = corresponding GPIO pin is configured as an input
0 = corresponding GPIO pin is configured as an output
* must bet set if corresponding analog channel is enabled (see ADCON1)
Legend:
R = Readable bit
- n = Value at POR
Unimplemented: Read as '0’
GP6:GP0: GPIO Bits
1 = corresponding GPIO pin output latch is a ‘1’
0 = corresponding GPIO pin output latch is a ‘0’
Legend:
R = Readable bit
- n = Value at POR
GP7TXC:GP0TXC: Transmit-on-change Enable bits
1 = Enable Transmit-On-Change/Compare For Corresponding GPIO/AN Channel
0 = Disable Transmit-On-Change/Compare For Corresponding GPIO/AN Channel
