DESCRIPTION
The DS1830 Programmable MicroMonitor monitors
three vital conditions for a microprocessor: power sup-
ply, software execution, and external override. All moni-
tored parameters are programmable, with values stored
in nonvolatile EPROM. This allows parameters such as
reset time, watchdog timeout period, and power supply
tolerance to be programmed into the device and tailored
to the application circuit and microprocessor which is to
be monitored.
In addition, the watchdog timer, reset, and pushbutton
functions may be disabled via software. This allows
maximum flexibility for use in new product development
and system application testing.
