CHAPTER 11 8/16-BIT COMPOSITE TIMER
11.1 Overview
■ PWC Timer Function
When the PWC timer function is selected, the width and cycle of an external input pulse can be
measured.
In this operating mode, the counter starts counting from "0x00" immediately after a count start
edge of an external input signal is detected. Afterward, when a count end edge is detected, the
counter transfers its value to a register to generate an interrupt.
■ Input Capture Function
When the input capture function is selected, the counter value is stored in a register
immediately after the detection of an edge of an external input signal.
This function is available in either free-run mode or clear mode for count operation.
In clear mode, the counter starts counting from "0x00", and transfers its value to a register to
generate an interrupt after an edge is detected. Afterward, the counter restarts counting from
"0x00".
In free-run mode, the counter transfers its value to a register to generate an interrupt
immediately after the detection of an edge. Afterward, unlike in clear mode, the counter
continues to count without being cleared to "0x00".
