TRISA<3> always reads ‘1’.
TRISA<5:4> always reads ‘1’ in XT, HS and LP Oscillator modes.
Unimplemented: Read as ‘0’
RA<5:0>: PORTA I/O Pin bit
1 = Port pin is > V
0 = Port pin is < V
Unimplemented: Read as ‘0’
TRISA<5:0>: PORTA Tri-State Control bits
1 = PORTA pin configured as an input (tri-stated)
0 = PORTA pin configured as an output
