FUNCTIONAL DESCRIPTION
Processor Reset
The CAT705, CAT706 & CAT813 detect supply voltage
(V CC ) conditions that are below the specified voltage trip
value (V RST ) and provide a reset output to maintain correct
system operation. On power ? up, RESET (or RESET for the
CAT813) are kept active for a minimum delay t RP of 140 ms
after the supply voltage (V CC ) rises above V RST to allow the
power supply and processor to stabilize. When V CC drops
below the voltage trip value (V RST ), the reset output signals
RESET (or RESET) are pulled active. RESET (or RESET)
is specifically designed to provide the reset input signals for
processors. This provides reliable and consistent operation
Manual Reset
The CAT705, CAT706 & CAT813 each have a Manual
Reset (MR) input to allow for alternative control of the reset
outputs. The MR input is designed for direct connection to
a pushbutton (see Figure 4). The MR input is internally
pulled up by 60 k W resistor and must be pulled low to cause
the reset output to go active. Internally, this input is
debounced and timed such that RESET (or RESET) signals
of at least 140 ms minimum will be generated. The min
140 ms t RP delay commences as the Manual Reset input is
released from the low level. (see Figure 5).
as power is turned on, off or during brownout conditions by
maintaining the processor operation in known conditions.
