When a break function is activated (BA bit =1 and BREN1/BREN2 =1):
When the break function is deactivated after applying the break (BA bit goes from 1 to 0 by
software), Timer takes the control of PWM ports.
The break function of the ST7FOXK2 is different from the break function of the
ST7FOXF1/ST7FOXK1. Refer to
function on page 88
Figure 41. ST7FOXF1/ST7FOXK1 Block diagram of break function
The break pattern (PWM[3:0] bits in the BREAKCR) 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.
