(3-4Tcy), fixed interrupt latency
(3Tcy) jump to high priority ISR code
unprotected code space
(1Tcy) TMR1 overflow?
(2Tcy) No, check another interrupt source
wait for TMR1L<0> to become clear
may already be clear (loops for 0 to 30.5us)
wait for TMR1L<0> to become set
(loops for 30.5us)
reload for next 1 second overflow
clear flag
record second
Another interrupt source...
code for other interrupts, if needed
;Select system clock for Timer1.
;Sample low byte of Timer1 before increments.
;Add reload value for low byte
;if this generates a carry then
;modify the reload value for the high byte.
;Reload Timer1 high byte.
;Reload Timer1 low byte.
;Timer1 off.
;Select external crystal.
;Timer1 on.
;Timer has just incremented, 31μs before next rising
edge to complete reload.
