HI TO ALL ENGINEERS.

I AM HAVING DIFFICULTY TO UNDERSTAND REAL PURPOSE OF BANK SWITCHING.
THIS IS THE WAY I UNDERSTAND.

1. BECAUSE OF PORTS ARE LOCATED IN BANK 1 AND DEFAULT IS 0 WE NEED TO
SWITCH THE
BANK IN ORDER TO SET THE PORTS.

        BSF     STATUS,RPO
        MOVLW   B'00000000'
        MOVWF   TRISB           ;MAKE PORTB OUTPUT
        MOVLW   B'11111111'
        MOVWF   TRISA           ;MAKE PORTA INPUT
        BCF     STATUS,RPO

SINCE IN BANK1 WE HAVE RAM TO USE WHY ALWAYS WE SWITCH BACK TO BANK 0.
WE CAN USE BANK1 WHEN EVER IT IS FULL THEN JUMP TO BANK 0.

IF ABOVE PORT SETTING IS CORRECT USING EMULATOR STEP ICON OR (F7) WHAT
EVER
CONNECTED ON PORTB (OUTPUT) GOES HIGH FOR A MOMENT .WHAT AM I DOING
WRONG TO
SET THE PORT. I AM USING PIC16C62.

ANDRE                           THANK YOU VERY MUCH.
