■ Interrupt Request Generation
The 16-bit pulse width counter can generate the following three interrupt requests:
•
Capture data transfer interrupt request
When capture data is transferred to the PWC data register, the interrupt flag is set. When
interrupt requests are enabled, an interrupt request is generated.
•
Counter overflow interrupt request
When the counter value overflows from FFFF
flag is set. When interrupt requests are enabled, an interrupt request is generated.
Capture is not performed in overflow.
•
Interrupt request which counts exceeding the value of upper register during counting
When the counter value is larger than the upper setting register during measurement, the flag
is set. When interrupt requests are enabled, an interrupt request is generated.
