General-Purpose Time Base/Free-Running Timer

10.1 Overview

This LSI has a time base timer and an 8-bit free-running timer (timer 6).
The time base timer is a 15-bit timer counter.
10.1.1

Functions

Table:10.1.1 shows the clock source and the interrupt generation cycle that can be used for the timer 6 and the
time base timer.
