Section 12   Watchdog Timer (WDT)

12.1

Overview

The SuperH microcomputer has a one-channel watchdog timer (WDT) for monitoring system
operations. If the system becomes uncontrolled and the timer counter overflows without being
rewritten correctly by the CPU, an overflow signal (

WDTOVF

) is output externally. The WDT

can simultaneously generate an internal reset signal for the entire chip.

When this watchdog function is not needed, the WDT can be used as an interval timer. In the
interval timer operation, an interval timer interrupt is generated at each counter overflow. The
WDT is also used in recovering from standby mode.

12.1.1

Features

WDT features are listed below:

• 

Watchdog timer mode interval timer mode can be selected.

• 

Outputs 

WDTOVF

 in or watchdog timer mode. When the counter overflows in watchdog timer

mode, overflow signal 

WDTOVF

 is output externally. It is possible to select whether or not to

reset the chip internally when this happens. Either the power-on reset or manual reset signal
can be selected as the internal reset signal.

• 

Generates interrupts in interval timer mode. When the counter overflows, it generates an
interval timer interrupt.

• 

Used to clear standby mode.

• 

Selection of eight counter clock sources
