TRISIO5 TRISIO4 TRISIO3 TRISIO2 TRISIO1 TRISIO0

bit 7 bit 0

bit 7-6: Unimplemented: Read as ’0’

bit 5-0: TRISIO<5:0>: General Purpose I/O Tri-State Control bit

1 = GPIO pin configured as an input (tri-stated)

0 = GPIO pin configured as an output.

Note: TRISIO<3> always reads 1.

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 bit 0

bit 7-6 Unimplemented: Read as ‘0’

bit 5-4 WPU<5:4>: Weak Pull-up Register bit

1 = Pull-up enabled

0 = Pull-up disabled

bit 3 Unimplemented: Read as ‘0’

bit 2-0 WPU<2:0>: Weak Pull-up Register bit

1 = Pull-up enabled

0 = Pull-up disabled

Note 1: Global GPPU must be enabled for individual pull-ups to be enabled.

2: The weak pull-up device is automatically disabled if the pin is in Output mode

(TRISIO = 0).
