4.Set up EPA0 and EPA1.

— Load EPA0_CON with 68H (timer 1, compare mode, ass ert 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 ( time = 0) is matched first.

—Load T1CONTROL with C2H (enables timer 1, selects up-counting at f/4, and enables the divide-by-four prescaler).

5.Enable the EPA0 and EPA1 interrupts and select PTS service for them.

—Set INT_MASK.7 and INT_MASK1.0.

—Set PTSSEL.7 and PTSSEL.8.

6.Enable the interrupts and the PTS. The EI instruction enables interrupts; the EPTS instruction enables the PTS.
