Figure 16-35. PSC behaviour versus PSCn Input A in Mode 14
The output frequency is not modified by the occurence of significative edge of retriggering input.
Figure 16-36. PSC behaviour versus PSCn Input B in Mode 14
The output is disactivated while retriggering input is active.
The output of the PSC is set to an inactive state and the corresponding ramp is not aborted. The
output stays in an inactive state while the Retrigger/Fault input is actve. The PSC runs at con-
stant frequency.
AT90PWM2/3 : The retrigger event is taken into account only if it occurs during the correspond-
ing On-Time. In the case of the retrigger event is not taken into account, the following active
outputs remains active, they are not desactivated.
