PIC BTFSC and BTFSS not working on PORTA

Question

I've always blinked leds on PORTB in PIC16F628A.

Nowdays i need to do that on PORTA because I'm trying keypad matrix on PORTB.

The code below runs perfectly on RB3 of PORTB, but I doesn't in PORTA.

Here is the example in PORTA. I've tested and the problem is in BTFSS and BTFSC function... Because if I turn led off or on manually is functioning well. (also I've ommited delay_1s_routine code)

main
    ;*********CONFIGURACION LED**********
    clrf Puerto_Led
    movlw 0x07
    movwf CMCON
bsf STATUS,RP0
        clrf TRISA
bcf STATUS,RP0

loop
    call prende_apaga_Led
    call delay_1s_routine
goto loop


prende_apaga_Led
 btfsc PORTA,RA1    ;si esta en 0 salta el GOTO
 goto $+3
 bsf PORTA,RA1      ;Pongo en '1' el bit del Led Verde
 return
 bcf PORTA,RA1      ;Pongo en '1' el bit del Led Verde
return

Thanks in Advice!!

EDITED: Put real values on code

PD: Tested this instruction separately and works great - bsf PORTA,RA1 - bcf PORTA, RA1

Answer 1

I prefer:

Instead of going into techno quirks and philosophical debates, bypass the problem..

I always use shadow registers for port states and test and drive over them.

So use a bit in your RAM to reflect the state of PORTA, RA1. Trust me it will work seamlessly.
