When a break function is activated (BAx bit =1 and BREN1/BREN2 =1):

When the break function is deactivated after applying the break (BAx bit go from 1 to 0 by
software), Timer takes the control of PWM ports.

Output compare mode
To use this function, load a 12-bit value in the Preload DCRxH and DCRxL registers.

The break pattern (PWM[3:0] bits in the BREAKCR1) is forced directly on the PWMx
output pins if respective OEx is set. (after the inverter).
The 12-bit PWM counter CNTR1 is put to its reset value, i.e. 00h (if BREN1 = 1).
The 12-bit PWM counter CNTR2 is put to its reset value,i.e. 00h (if BREN2 = 1).
ATR1, ATR2, Preload and Active DCRx are put to their reset values.
Counters stop counting.
