Figure 40. 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 BREAK pin. This can be selected by using
the BRSEL bit in BREAKCR register. In order to use the break function it must be previously
enabled by software setting the BPEN bit in the BREAKCR register.
The Break active level can be programmed by the BREDGE bit in the BREAKCR register.
When an active level is detected on the BREAK pin, the BA bit is 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 BA bit to activate the break function without using the BREAK pin. 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.
