Problem:
| | Some PIC chips, that have A/D convertors built into them, initialise with the pins in analogue mode. This means that the input/output initialisation has ne effect on these pins.
| |
|
Solution:
| |
In order to ensure that port pins are initialised into digital mode, write the value of seven (7) to register 1F of register bank 1.
BSF 3, 5 ;Go to register bank 1
MOVLW 0x07
MOVWF 0x1F
BCF 3, 5 ;Go back to register bank 0
