For the Power On / Low Voltage Reset function of the
X4023x, the RESET output may be driven HIGH down
to a V
CC
of 1V (V
RVALID
). See Figure 30. Another fea-
ture of the X4023x, is that the value of t
selected in software via the CR register (See “PUP1,
PUP0: Power On Reset bits – (Nonvolatile)” on
page 19.).

It is recommended to stop communication to the device
while RESET is HIGH. Also, setting the Manual Reset
(MR) pin HIGH overrides the Power On / Low Voltage
circuitry and forces the RESET output pin HIGH (See
"MR: Manual Reset").
MR: Manual Reset
The RESET output can be forced HIGH externally
using the Manual Reset (MR) input. MR is a de-
bounced, TTL compatible input, and so it may be oper-
ated by connecting a push-button directly from V
the MR pin.

RESET remains HIGH for time t
returned to its LOW state (See Figure 19). An external
“pull down” resistor is required to hold this pin (nor-
mally) LOW.
