    Using TRIS and BANKSEL instruction in MPLAB

    Re: MP ASM warning thanks Tagli, i have managed to makre it run i changed SHIFT EQU 0x0C to 0xFF although i get some massages of not being in bank 0 when i assemble the progrm next i changed the bit b'01001001' to b'00000001' and i can see the LEDs switching ON in this order from B0 ....B7...
