idle is applied to a single output. When the push-pull mode is enabled, the IPPSTAT flag in
HRTIM_TIMxISR indicates during which period the delayed protection request occurred.
This mode is available whatever the timer operating mode (regular, push-pull, deadtime). It
is available with 2 external events only:
• hrtim_eev6 and hrtim_eev7 for timer A, B and C
• hrtim_eev8 and hrtim_eev9 for timer D, E and F
The delayed protection mode can be triggered only when the counter is enabled (TxCEN bit
set). It remains active even if the TxEN bit is reset, until the TxyOEN bits are set.
Figure 228. Delayed Idle mode entry
The delayed idle mode has a higher priority than the burst mode: any burst mode exit
request is discarded once the delayed idle protection has been triggered. On the contrary, If
the delayed protection is exited while the burst mode is active, the burst mode is resumed
normally and the output is maintained in the idle state until the burst mode exits. Figure 229
gives an overview of these different scenarios.
