162 CHAPTER 9 WATCHDOG TIMER (1) Watchdog timer mode A runaway is detected. Upon detection of the runaway, a non-maskable interrupt request or RESET can be generated. Table 9-1. Watchdog Timer Runaway Detection Times Runaway Detection Times 2 12 × 1/fX (489 μs) 2 13 × 1/fX (978 μs) 2 14 × 1/fX (1.96 ms) 2 15 × 1/fX (3.91 ms) 2 16 × 1/fX (7.82 ms) 2 17 × 1/fX (15.6 ms) 2 18 × 1/fX (31.3 ms) 2 20 × 1/fX (125 ms) Remarks 1. fX: Main system clock oscillation frequency 2. Figures in parentheses are for operation with fX = 8.38 MHz (2) Interval timer mode Interrupt requests are generated at the preset time intervals. Table 9-2. Interval Times Interval Time 2 12 × 1/fX (489 μs) 2 13 × 1/fX (978 μs) 2 14 × 1/fX (1.96 ms) 2 15 × 1/fX (3.91 ms) 2 16 × 1/fX (7.82 ms) 2 17 × 1/fX (15.6 ms) 2 18 × 1/fX (31.3 ms) 2 20 × 1/fX (125 ms) Remarks 1. fX: Main system clock oscillation frequency 2.
