later detected, the count value of the 16-bit counter is stored in the TAAmCCRa register, the 16-bit counter is cleared
to 0000H, and a capture interrupt request signal (INTTAmCCa) is generated.
interrupt request signal (INTTAmOV) is generated at the next count clock, and the counter is cleared to 0000H and
continues counting. At this time, the overflow flag (TAAmOPT0.TAAmOVF bit) is also set to 1. Clear the overflow flag
to 0 by executing the CLR instruction via software.
When the TAAmCE bit is set to 1, the 16-bit counter starts counting. When the valid edge input to the TIAma pin is
The pulse width is calculated as follows.
If the valid edge is not input to the TIAma pin even when the 16-bit counter counted up to FFFFH, an overflow
If the overflow flag is set to 1, the pulse width can be calculated as follows.
Remark
Pulse width = Captured value × Count clock cycle
Pulse width = (10000H × TAAmOVF bit set (1) count + Captured value) × Count clock cycle
