PWC Timer Function
When the PWC timer function is selected, the width and cycle of an external input pulse can be measured.
In this operation mode, the counter starts counting from "00
external input signal and transfers the count value to a register to generate an interrupt upon detection of a
count end edge.
Input Capture Function
When the input capture function is selected, the counter value is stored in a register upon detection of an
edge for an external input signal.
This function is available in either free-run mode or clear mode for count operation.
In the clear mode, the counter starts counting from "00
interrupt upon detection of an edge. In this case, the counter continues to count from "00
In the free-run mode, the counter transfers its value to a register to generate an interrupt upon detection of
an edge. In this case, however, the counter continues to count without being cleared.
