CHAPTER  9   WATCHDOG  TIMER 

 

 

9.1  Functions of Watchdog Timer 

 

The watchdog timer operates on the internal low-speed oscillation clock. 

The watchdog timer is used to detect an inadvertent program loop.  If a program loop is detected, an internal reset 

signal is generated. 

Program loop is detected in the following cases. 

 

•

  If the watchdog timer counter overflows 

•

  If a 1-bit manipulation instruction is executed on the watchdog timer enable register (WDTE) 

•

  If data other than “ACH” is written to WDTE 

•

  If data is written to WDTE during a window close period 

•

  If the instruction is fetched from an area not set by the IMS and IXS registers (detection of an invalid check while 

the CPU hangs up) 

•

 If the CPU accesses an area that is not set by the IMS and IXS registers (excluding FB00H to FFFFH) by 

executing a read/write instruction (detection of an abnormal access during a CPU program loop) 

 

When a reset occurs due to the watchdog timer, bit 4 (WDTRF) of the reset control flag register (RESF) is set to 1.  

For details of RESF, see
