Subsequently, when the edge opposite to the selected edge is detected, the up counter value is captured into
TA0DRB, an INTTCA0 interrupt request is generated, and TA0SR<TA0CPFB> is set to "1". Depending on
the TA0MOD<TA0MCAP> setting, the operation differs as follows:
this time, an INTTCA0 interrupt request occurs if the overflow interrupt control TA0CR<TA0OVE> is set
to "1".

The operation after capturing is determined by the pulse width measurement mode control
The operation to be executed in case of an overflow of the up counter can be selected at the overflow
Note that this mode uses the TA0 input pin, and the TCA0 pin must be set to the input mode beforehand
The operation is started by setting TA0CR<TA0S> to "1". In this time, TA0DRA and TA0DRB register
