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

pin values.
RA<7:0>: PORTA I/O Value bits
1 = Port pin is > V
0 = Port pin is < V
TRISA<7:6>: PORTA Tri-State Control bit
1 = PORTA pin configured as an input (tri-stated)
0 = PORTA pin configured as an output
TRISA5: RA5 Port Tri-State Control bit
This bit is always ‘1’ as RA5 is an input only
TRISA<4:0>: PORTA Tri-State Control bit
1 = PORTA pin configured as an input (tri-stated)
0 = PORTA pin configured as an output
LATA<7:6>: RA<7:6> Output Latch Value bits
Unimplemented: Read as ‘0’
LATA<4:0>: RA<4:0> Output Latch Value bits
