0: No remapping. UIF status bit is not copied to TIMx_CNT register bit 31.
1: Remapping enabled. UIF status bit is copied to TIMx_CNT register bit 31.
This bit-field indicates the division ratio between the timer clock (CK_INT) frequency and the
dead-time and sampling clock (t
(TIx),

11: Reserved, do not program this value
0: TIMx_ARR register is not buffered
1: TIMx_ARR register is buffered
0: Counter is not stopped at update event
1: Counter stops counting at the next update event (clearing the bit CEN)
This bit is set and cleared by software to select the UEV event sources.
0: Any of the following events generate an update interrupt or DMA request if enabled.
These events can be:
– Counter overflow/underflow
– Setting the UG bit
– Update generation through the slave mode controller
1: Only counter overflow/underflow generates an update interrupt or DMA request if
enabled.
