Capture Initialization
shows the initialization of compare mode, and
; CCP Module is off
; Clear Timer1 High byte
; Clear Timer1 Low byte
; Disable interrupts and clear T0IF
; Bank1
; Make CCP pin input
; Disable peripheral interrupts
; Bank0
; Clear peripheral interrupts Flags
; Capture mode, every 4th rising edge
;
; This needs to be done before next compare
