System reset with built-in watchdog timer
2001 Aug 22
12
The values of RCT and CT affect the watchdog monitoring time
(tWDM), the watchdog reset time (tWDR), and power-on reset delay
time (tPR). See Formula 1 in the AC Electrical Characteristics and
the Timing diagram shown in Figure 20 for parameter definitions.
Also see Figures 11 through 18 for typical time relationship
performance.
The effect of RCT on the watchdog timer monitoring time at room
temperature for CT = 0.1 mF is shown in Figure 25.
