4.3 Watchdog Timer

4.3.1 Configuration of watchdog timer

The S1C63616 has a built-in watchdog timer that operates with a 256 Hz divided clock from the OSC1 as
the source clock. The watchdog timer starts operating after initial reset, however, it can be stopped by the
software. The watchdog timer must be reset cyclically by the software while it operates. If the watchdog
timer is not reset in at least 3–4 seconds, it generates a non-maskable interrupt (NMI) to the CPU.
Figure 4.3.1.1 is the block diagram of the watchdog timer.

Fig. 4.3.1.1 Watchdog timer block diagram

The watchdog timer contains a 10-bit binary counter, and generates the non-maskable interrupt when the
last stage of the counter (0.25 Hz) overflows.
Watchdog timer reset processing in the program's main routine enables detection of program overrun, such
as when the main routine's watchdog timer processing is bypassed. Ordinarily this routine is incorporated
where periodic processing takes place, just as for the timer interrupt routine.
The watchdog timer operates in the HALT mode. If a HALT status continues for 3–4 seconds, the non-
maskable interrupt releases the HALT status.

4.3.2 Interrupt function

If the watchdog timer is not reset periodically, the non-maskable interrupt (NMI) is generated to the core
CPU. Since this interrupt cannot be masked, it is accepted even in the interrupt disable status (I flag = "0").
However, it is not accepted when the CPU is in the interrupt mask state until SP1 and SP2 are set as a pair,
such as after initial reset or during re-setting the stack pointer. The interrupt vector of NMI is assigned to
0100H in the program memory.
