Bits 7:0 CCR4[15:8]: Capture/compare value (MSB)
If the CC4 channel is configured as output (CC4S bits in TIM1_CCMR4 register):
The value of CCR4 is loaded permanently into the actual capture/compare 4 register if the preload
feature is not enabled (OC4PE bit in TIM1_CCMR4). Otherwise, the preload value is copied in the
active capture/compare 4 register when a UEV occurs.The active capture/compare register contains
the value which is compared to the counter register, TIM1_CNT, and signalled on the OC4 output.
If the CC4 channel is configured as input (CC4S bits in TIM1_CCMR4 register):
The value of CCR4 is the counter value transferred by the last input capture 4 event (IC4).
