4. Set up EPA0 and EPA1:
— Load EPA0_CON with 68H (timer 1, compare mode, assert output pin, re-enable).
— Load EPA1_CON with 158H (timer 1, compare mode, deassert output pin, re-enable,
remap enabled).
— Load EPA0_TIME with 0000H (selects time 0 as first event time for EPA0).
— Load EPA1_TIME with the value of T1 (selects time T1 as first event time for EPA1).
— Load timer 1 with FFFFH to ensure that the EPA0 event time (t = 0) is matched first.
— Load T1CONTROL with C2H (enables timer 1, selects up-counting at F
OSC
/4, and
enables the divide-by-four prescaler).
5. Enable the EPA0 and EPA1 interrupts and select PTS service for them:
— Set INT_MASK.4 and INT_MASK.3.
