Bits 15:0 CCR3[15:0]: Capture/Compare value
If channel CC3 is configured as output: CCR3 is the value to be loaded in the actual
capture/compare 3 register (preload value).
It is loaded permanently if the preload feature is not selected in the TIMx_CCMR2 register
(bit OC3PE). Else the preload value is copied in the active capture/compare 3 register when
an update event occurs.
The active capture/compare register contains the value to be compared to the counter
TIMx_CNT and signalled on OC3 output.
If channel CC3 is configured as input: CCR3 is the counter value transferred by the last
input capture 3 event (IC3). The TIMx_CCR3 register is read-only and cannot be
programmed.
