bit 0

Legend:
R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7-6

Unimplemented: Read as ‘0’.

bit 5-0

RG<5:0>: PORTG General Purpose I/O Pin bits
1 = Port pin is > V

0 = Port pin is < V

bit 5

TRISG5: PORTG Tri-State Control bit
This bit (RG5 pin) is an input only and always read as ‘1’.

bit 4-0

TRISG<4:0>: PORTG Tri-State Control bits
1 = PORTG pin configured as an input (tri-stated)
0 = PORTG pin configured as an output

LATG<5:0>: PORTG Output Latch Value bits

Note 1:

Writes to PORTG are actually written to corresponding LATG register. Reads from PORTG register is return of actual
I/O pin values.
