LEVEL RESET, EDGE-TRIGGERED
HARDWARE LIMIT ONE-SHOT
MODES
In Level -Triggered One-Shot mode the timer count is
reset on the external signal level and starts counting
on the rising/falling edge of the transition from Reset
level to the active level while the ON bit is set. Reset
levels are selected as follows:
• Low Reset level (MODE<4:0> = 01110)
• High Reset level (MODE<4:0> = 01111)
When the timer count matches the PRx period count,
the timer is reset and the ON bit is cleared. When the
ON bit is cleared by either a PRx match or by software
control a new external signal edge is required after the
ON bit is set to start the counter.
When Level-Triggered Reset One-Shot mode is used
in conjunction with the CCP PWM operation the PWM
drive goes active with the external signal edge that
starts the timer. The PWM drive goes inactive when the
timer count equals the CCPRx pulse width count. The
PWM drive does not go active when the timer count
clears at the PRx period count match.
