The only thing I am doing in the ISR is the following:
Code:
ToggleLEDF:
     If F1=1 then Toggle PortA.0
     If F2=1 then Toggle PortA.1
     If F3=1 then Toggle PortA.2
@ INT_RETURN

'---[TMR2 - interrupt handler]--------------------------------------------------
ToggleLEDS:
     If S1=1 then Toggle PortA.0
     If S2=1 then Toggle PortA.1
     If S3=1 then Toggle PortA.2
	pause 100
@ INT_RETURN
