Figure 42. Dead time generation
In the above example, when the DTE bit is set:
With this programmable delay (Tdt), the PWM0 and PWM1 signals which are generated are
not overlapped.
Break function
The break function can be used to perform an emergency shutdown of the application being
driven by the PWM signals.
The break function is activated by the external BREAKx pins. This can be selected by using
the BRxSEL bits in BREAKCRx register. In order to use the break function it must be
previously enabled by software setting the BPENx bits in the BREAKCRx registers.
The Break active level can be programmed by the BRxEDGE bits in the BREAKCRx
registers. When an active level is detected on the BREAKx pins, the BAx bits are set and the
break function is activated. In this case, the PWM signals are forced to BREAK value if
respective OEx bit is set in PWMCR register.
Software can set the BAx bits to activate the break function without using the BREAKx pins.
The BREN1 and BREN2 bits in the BREAKEN register are used to enable the break
activation on the 2 counters respectively. In Dual Timer mode, the break for PWM2 and
PWM3 is enabled by the BREN2 bit. In Single Timer mode, the BREN1 bit enables the
break for all PWM channels.
