Output not affected by
STMAF flag. Remains High
until reset by STON bit
Output Pin
Reset to Initial value
Output controlled by
other pin-shared function
Output Inverts

No STMAF flag
generated on
CCRA overflow
Output does
not change
Compare Match Output Mode – STCCLR=1
Note: 1. With STCCLR=1 a Comparator A match will clear the counter
2. The STM output pin is controlled only by the STMAF ag
3. The output pin is reset to its initial state by a STON bit rising edge
4. A STMPF ag is not generated when STCCLR=1
