At power-up, WDO goes high after tD-PO (see Figure 3).
The initial watchdog timeout period (tWDI) applies imme-
diately after WDO is high. The initial watchdog timeout
period allows the P to perform its initialization process.
A normal watchdog timeout period (tWD) applies when-
ever WDI transitions from high to low after the initial
watchdog timeout period occurs. WDI monitors the tog-
gling output of the P, indicating normal processor
behavior. If WDI does not toggle during the normal
watchdog timeout period (tWD), indicating that the
processor has stopped operating or is stuck in an infinite
execution loop, WDO goes low. WDO stays low until the
next transition on WDI. An initial watchdog timeout peri-
od (tWDI) starts when WDO goes high.
If WDO is connected to MR, the WDO will assert for a
short duration (~5s), long enough to assert the RESET
output. Asserting RESET clears the watchdog timer and
WDO goes high. The reset output will remain asserted
for its timeout period after a watchdog fault. The watch-
dog timer stays cleared as long as RESET is low.
Applications Information
Layout and Bypassing
For better noise immunity, bypass each of the voltage-
detector inputs to GND with 0.1F capacitors installed
as close to the device as possible. Bypass VCC and BP
to GND with 1F capacitors installed as close to the
device as possible. VCC (when not externally supplied)
and BP are internally generated voltages and should
not be used to supply power to external circuitry.
