The CC4NP bit in the TIMx_CCER register should be listed in the reference manual in the section "17.4.9 TIM1 and TIM8 capture/compare enable register (TIMx_CCER)". Currently, only the CC1NP, CC2NP, and CC3NP bits are listed. The sections for the other timers correctly list this bit.
This bit is used when channel 4 is configured in input capture (IC) mode to help determine if triggers occur on rising and/or falling edges.
I checked the latest RM0090 (rev18) reference manual and the bit is not listed in there in this section.
