Description
Input Capture/Output Compare Channel “x” Flag — These flags are set when an input capture or output
compare event occurs. Clear a channel flag by writing one to it.
When TFFCA bit in TSCR register is set, a read from an input capture or a write into an output compare channel
(0x0010–0x001F) will cause the corresponding channel flag CxF to be cleared.
