CAPIF
Timer External Capture Interrupt Flag
This bit indicates the timer external capture interrupt flag status.
0 = Tx_EXT (x= 0~3) pin interrupt did not occur.
1 = Tx_EXT (x= 0~3) pin interrupt occurred.
Note1:
This bit is cleared by writing 1 to it.
Note2:
When CAPEN (TIMERx_EXTCTL[3]) bit is set, CAPFUNCS (TIMERx_EXTCTL[4])
bit is 0, and a transition on Tx_EXT (x= 0~3) pin matched the CAPEDGE
(TIMERx_EXTCTL[2:1]) setting, this bit will set to 1 by hardware.
Note3:
There is a new incoming capture event detected before CPU clearing the CAPIF
status. If the above condition occurred, the Timer will keep register TIMERx_CAP
unchanged and drop the new capture value.
