; Stop Timer2, Prescaler = 1:1,
;
; Clear Timer2 register
; Disable interrupts
; Bank1
; Disable peripheral interrupts
; Bank0
; Clear peripheral interrupts Flags
; Postscaler = 1:15, Prescaler = 1:16
;
; Has TMR2 interrupt occurred?
; NO, continue loop
; YES, clear flag and continue.
Postscaler = 1:1
Timer2 is off
