APPLICATION INFORMATION (cont.)
t1:
Microprocessor is reset.
t2:
WDI is toggled some time after reset, but before
T
WP
expires.
t3:
WDI is toggled before T
WP
expires.
t4:
WDI is toggled before T
WP
expires.
t5:
WDI is not toggled before T
WP
expires and WDO
asserts low, triggering the microprocessor to enter an
error recovery routine.
t6:
The microprocessor’s error recovery routine is exe-
cuted and WDI is toggled, reinitiating the watchdog
timer.
t7:
WDI is toggled before T
WP
expires.
t8:
WDI is toggled before T
WP
expires.
t9:
RES is momentarily triggered, RES is asserted low
for T
RP
.
t10:
Microprocessor is reset, RES pulls high.
t11:
WDI is toggled some time after reset, but before
T
WP
expires.
t12:
WDI is toggled before T
WP
expires.
t13:
WDI is toggled before T
WP
expires.
t14:
V
DD
dips below the reset threshold, RES is as-
serted.
