Compare Initialization
; CCP Module is off
; Clear Timer1 High byte
; Clear Timer1 Low byte
; Disable interrupts and clear T0IF
; Bank1
; Make CCP pin output if controlling state of pin
; Disable peripheral interrupts
; Bank0
; Clear peripheral interrupts Flags
; Compare mode, set CCP1 pin on match
;
; This needs to be done before next compare
