7.1 Overview
The H8/325 Series has an on-chip 16-bit free-running timer (FRT) module that uses a 16-bit free-
running counter as a time base. Applications of the FRT module include rectangular-wave output
(up to two independent waveforms), input pulse width measurement, and measurement of external
clock periods.
7.1.1 Features
The features of the free-running timer module are listed below.
• Selection of four clock sources
• Two independent comparators
• Input capture
• Counter can be cleared under program control
• Four interrupt sources
• Noise canceler
7.1.2 Block Diagram
Figure 7-1 shows a block diagram of the free-running timer.
The free-running counter can be driven by an internal clock source (Ø/2, Ø/8, or Ø/32), or an
external clock input (enabling use as an external event counter).
Each comparator can generate an independent waveform.
The current count can be captured on the rising or falling edge (selectable) of an input signal.
The free-running counter can be cleared on compare-match A.
Compare-match A and B, input capture, and overflow interrupts are requested independently.
A built-in noise canceler can remove high-frequency noise from the pulse signal input at the
input capture pin.
