Capture Counter Value Transferred to CHxCCR
When the channel is used as a capture input, the counter value is captured into the Channel Capture
/ Compare Register (CHxCCR) when an effective input signal transition occurs. Once the capture
event occurs, the CHxCCIF flag in the INTSR register is set accordingly. If the CHxCCIF bit is
already set, i.e., the flag has not yet been cleared by software, and another capture event on this
channel occurs, the corresponding channel Over-Capture flag, named CHxOCF, will be set.
