Jul 15, 2010
The watchdog timer is mounted onto all 78K0/Kx2 microcontroller products.
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
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
• If the CPU accesses an area that is not set by the IMS and IXS registers (excluding FB00H to FFCFH and FFE0H to
When a reset occurs due to the watchdog timer, bit 4 (WDTRF) of the reset control flag register (RESF) is set to 1. For
