RAM Write Protection
The CE OUT line drives the Chip Select inputs of the CMOS
RAM. CE OUT follows CE IN as long as V CC is above the reset
threshold. If V CC falls below the reset threshold, CE OUT goes
high, independent of the logic level at CE IN . This prevents the
microprocessor from writing erroneous data into RAM during
power-up, power-down, brownouts and momentary power in-
terruptions. The LOW LINE output goes low when V CC falls
below the reset threshold.
RESET also goes low if the Watchdog Timer is enabled and
WDI remains either high or low for longer than the watchdog
timeout period.
The RESET output has an internal 1.6 mA pullup, and can ei-
ther connect to an open collector RESET bus or directly drive a
CMOS gate without an external pullup resistor.

The microprocessor drives the WATCHDOG INPUT (WDI)
with an I/O line. When OSC IN and OSC SEL are uncon-
nected, the microprocessor must toggle the WDI pin once every
1.6 seconds to verify proper software execution. If a hardware or
softwar e failure occurs such that WDI not toggled a 200 ms
RESET pulse will be generated after 1.6 seconds. This typi-
cally restarts the microprocessor’s power-up routine. A new
RESET pulse is issued every 1.6 seconds until WDI is again
strobed.

dog timer is not serviced within its timeout period. Once WDO
goes low it remains low until a transition occurs at WDI. The
watchdog timer feature can be disabled by leaving WDI uncon-
nected. OSC IN and OSC SEL also allow other watchdog tim-
ing options.
