Information missing in reference manual for register clearing interrupt status on G431

[Tobe]

There is not information, on how to clear the flag (1 or 0), on register TIMx_SR (x=1,8,20).

I believe there were also other registers where it was not mentioned, how to clear them.

rc_w0 means you write zero to the bit to clear it, ie TIM->SR= 0xFFFFFFFE; clears UIF

"read/clear write0 (rc_w0) Software can read as well as clear this bit by writing 0. Writing 1 has no
effect on the bit value."

Page 73 says it all.

Thats a bit embarrasing 😅
