Chapter 48 Clock Monitor

1. Overview

The Clock Monitor is a macro that outputs internal clock signals to a terminal to externally monitor them. The Clock
Monitor provides a function to divide the frequency of a clock signal before it outputs to the terminal, thus allowing the
clock signal to be used as an event at which external circuits act in synchronization with a MCU function.

2. Features

• Format: Divide an internal clock signal to output it to a terminal (MONCLK).

• Channel: 1

• Division ratios: CLK/1, CLK/2, CLK/3, ..., CLK/16

• Glitch free output enable

• Programmable mark level (output “L” or “H” before enabling the clock output)

• Interrupt: None
