Function
Enable Compare Timer 1 count direction change interrupt
status
If ECTC = 0, the Compare Timer 1 count change interrupt is
disabled.
Compare timer 1 operating mode 0:
Bit has no effect on the interrupt generation.
Compare timer 1 operating mode 1:
If ECTC = 1, an interrupt is generated when Compare Timer 1
reaches count value 0000_H and changes its count direction from
down- to up-counting.
Capture/Compare rising edge interrupt enable
Capture Mode:
If CCxREN is set, an interrupt is generated at a low-to-high
transition (rising edge) of the corresponding CCx input signal.
Compare Mode:
If CCxREN is set, an interrupt is generated if the Compare
Timer 1 value matches the compare register CCx value during
the up-counting phase of the Compare Timer 1. This function is
available in both Compare Timer 1 operating modes.
Capture/Compare falling edge interrupt enable
Capture Mode:
If CCxFEN is set, an interrupt is generated at a high-to-low
transition (falling edge) of the corresponding CCx input signal.
Compare Mode:
If CCxFEN is set, an interrupt is generated only in Compare timer
mode 1 if the Compare Timer 1 value matches the Compare
register CCx value during the down-counting phase of the
Compare Timer 1. This function is available only in Compare
Timer 1 operating mode 1.
