This LSI incorporates two watchdog timer channels (WDT_0 and WDT_1). The watchdog timer
can output an overflow signal (RESO) externally if a system crash prevents the CPU from writing
to the timer counter, thus allowing it to overflow. Simultaneously, it can generate an internal reset
signal or an internal NMI interrupt signal.
When this watchdog function is not needed, the WDT can be used as an interval timer. In interval
timer operation, an interval timer interrupt is generated each time the counter overflows. A block
diagram of the WDT_0 and WDT_1 are shown in figure 13.1.
13.1
• Selectable from eight (WDT_0) or 16 (WDT_1) counter input clocks.
• Switchable between watchdog timer mode and interval timer mode
Watchdog Timer Mode:
•
• When the LSI is selected to be internally reset at counter overflow, a low level signal is output
Internal Timer Mode:
•
WDT0102A_000120020900
from the RESO pin if the counter overflows.
If the counter overflows, an internal reset or an internal NMI interrupt is generated.
If the counter overflows, an internal timer interrupt (WOVI) is generated.
