just a few thoughts. ( i am reading the 12c50x specs and assuming things are
the same for the other chips)

1. by loading H'00' into the OPTION register you have a sleep time of ~18ms.
use the prescale to change this time to a longer value (1:128 = ~2.3 sec)
(1:16 might be a good value to play with)

2. when the pic wakes up from sleeping it resets the program counter. that
is why the inc 6,1 is never executed. i don't think you need any code after
the sleep.
