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