Any of the four open-drain ports can be configured as a

logic input by setting the port output logic-high (logic-high

for an open-drain output is high impedance). When the

MAX7323 is read through the serial interface, the actual

logic levels at the ports are read back.

Initial Power-Up

On power-up, the transition detection logic is reset, and

INT is deasserted. The interrupt mask register is set to

0x3C, enabling the interrupt output for transitions on

all four input ports. The transition flags are cleared to

indicate no data changes. The power-up default state of

The four ports offer latching transition detection

functionality. All input ports are continuously monitored for

changes. An input change sets 1 of 4 flag bits that identify

changed input(s). All flags are cleared upon a subsequent

read or write transaction to the MAX7323.

the four push-pull outputs is set according to the I C slave

address selection inputs, AD0 and AD2 (see Table 3).

Power-On Reset

The MAX7323 contains an integral power-on-reset (POR)

circuit that ensures all registers are reset to a known state

on power-up. When V+ rises above V

POR circuit releases the registers and 2-wire interface

for normal operation. When V+ drops to less than V

A latching interrupt output, INT, automatically flags data

changes on any of the I/O ports used as inputs. The

interrupt output INT, and all transition flags are

deasserted when the MAX7323 is next accessed through

the serial interface.

(1.6V max), the

POR

the MAX7323 resets all ports to the POR defaults (see

Table 3).

Internal pullup resistors to V+ are selected by the address

select inputs, AD0 and AD2. Pullups are enabled on the

input ports in groups of two (see Table 3).

RST Input

The active-low RST input operates as a reset that voids

Use the slave address selection to ensure that I/O ports

used as inputs are logic-high on power-up. I/O ports with

internal pullups enabled default to a logic-high output

state. I/O ports with internal pullups disabled default to a

logic-low output state. Output port power-up logic states

are selected by the address select inputs AD0 and AD2.

Ports default to logic-high or logic-low on power-up in

groups of two (see Table 3).

any current I C transaction involving the MAX7323,

forcing the MAX7323 into the I C STOP condition. The

reset action does not clear the interrupt output (INT).

Standby Mode

When the serial interface is idle, the MAX7323

automatically enters standby mode, drawing minimal

supply current.
