Output does
not change
Output not affected by
CTMAF flag. Remains High
until reset by CTON bit
Output Pin
Output Inverts
when CTPOL is high
Note CTIO [1:0] = 10
Active High Output select
Reset to Initial value
Output controlled by other
pin-shared function
Compare Match Output Mode – CTCCLR=1
Note: 1. With CTCCLR=1, a Comparator A match will clear the counter
2. The CTM output pin controlled only by the CTMAF flag
3. The output pin reset to initial state by a CTON rising edge
4. The CTMPF flags is not generated when CTCCLR=1
