x = unknown, u = unchanged, - = unimplemented locations read as ‘0’. Shaded cells are not used by PORTA.
This value applies only to the PIC16F87.
This value applies only to the PIC16F88.
Pin 5 is an input only; the state of the TRISA5 bit has no effect and will always read ‘1’.
PIC16F88 device only.
