WATCHDOG TIMER
Figure 4. Watchdog Restart
The Watchdog Timer circuit monitors the microproces-
sor activity by monitoring the SDA and SCL pins. A
standard read or write sequence to any slave address
SCL
.6μs
1.3μs
byte restarts the watchdog timer and prevents the
WDO signal going active. A minimum sequence to
reset the watchdog timer requires four microprocessor
SDA
instructions namely, a Start, Clock Low, Clock High
and Stop. The state of two nonvolatile control bits in
Start
WDT Reset
Stop
the Status Register determine the watchdog timer
period. The microprocessor can change these watch-
dog bits by writing to the X40430, X40431, X40434,
X40435 control register (also refer to page 20).

V1, V2 AND V3 THRESHOLD PROGRAM
PROCEDURE (OPTIONAL)
The X40430 is shipped with standard V1, V2 and V3
threshold (V TRIP1, V TRIP2, V TRIP3 ) voltages. These
values will not change over normal operating and stor-
age conditions. However, in applications where the
standard thresholds are not exactly right, or if higher
precision is needed in the threshold value, the X40430,
X40431, X40434, X40435 trip points may be adjusted.
The procedure is described in the following situation,
and uses the application of a high voltage control sig-
nal.
