CHAPTER 10 WATCHDOG TIMER

User’s Manual U16899EJ2V0UD

232

Table 10-2. Option Byte Setting and Watchdog Timer Operation Mode

Option Byte

Ring-OSC Cannot Be Stopped

Ring-OSC Can Be Stopped by Software

Watchdog timer clock

source

Fixed to f

Note 1

•

Selectable by software (f

, f

or stopped)

•

When reset is released: f

Operation after reset

Operation starts with the maximum interval

Operation starts with maximum interval

Operation mode selection

The interval can be changed only once.

The clock selection/interval can be changed

only once.

Features

The watchdog timer cannot be stopped.

The watchdog timer can be stopped in

standby mode

Note 2

Notes 1. As long as power is being supplied, Ring-OSC oscillation cannot be stopped (except in the reset

period).

2. The conditions under which clock supply to the watchdog timer is stopped differ depending on the

clock source of the watchdog timer.

<1> If the clock source is f

, clock supply to the watchdog timer is stopped under the following

conditions.

•

When f

is stopped

•

In HALT/STOP mode

•

During oscillation stabilization time

<2> If the clock source is f

, clock supply to the watchdog timer is stopped under the following

conditions.

•

If the CPU clock is f

and if f

is stopped by software before execution of the STOP instruction

•

In HALT/STOP mode

Remarks 1. f

: Ring-OSC clock oscillation frequency

2. f

: High-speed system clock oscillation frequency
