There's no built-in command to read a comparator status. you need to read the register.
this something to start...
Code:
@ __config _INTRC_OSC_NOCLKOUT & _MCLRE_OFF
TRISIO = %11001111 ' GPIO.4, GPIO.5 as output
CMCON = %00000010 ' COUT=1 when Vin+(GPIO.0) > Vin- (GPIO.1)
' comparator mode :comparator without output
Clip var GPIO.4
Normal var GPIO.5
Speaker var byte
start:
speaker=CMCON.6 ' read from internal comparator
Select case speaker
case 0
clip=0
normal=1
case 1
clip=1
normal=0
pause 100
Clip=0
end select
goto start

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
