High-resolution timer (HRTIM)

The auto-delayed compare is only valid from the capture up to the period event: once the

counter has reached the period value, the system is re-armed with compare disabled until a

capture occurs.

DELCMP2[1:0] and DELCMP4[1:0] bits in HRTIM_TIMxCR register allow to configure the

auto-delayed mode as follows:

Regular compare mode: HRTIM_CMP2xR and HRTIM_CMP4xR register contents are

directly compared with the counter value.

Auto-delayed mode: compare 2 and compare 4 values are recomputed and used for

comparison with the counter after a capture 1/2 event.

Auto-delayed mode with timeout: compare 2 and compare 4 values are recomputed

and used for comparison with the counter after a capture 1/2 event or after a compare 1
