Strange behavior of PICmicro I/O pin

Hi Ravi,
Try putting nops in like this:
bsf portc,scl
nop
bsf portc,sda
goto $+1
bcf portc,scl
nop
bcf portc,sda
goto $-5
If it works then it is probably a read-write-modify issue, which occurs
when a pin hasn't changed enough before the next bcf or bsf happens.
Cheerful regards,
Bob
