MAX7326
I2C Port Expander with 12 Push-Pull Outputs
and 4 Inputs
______________________________________________________________________________________

The master can read 2 bytes from the group A ports of the
MAX7326 and then issues a STOP condition (Figure 7). In
this case, the MAX7326 transmits the current port data,
followed by the transition flags. The transition flags are
then cleared, and transition detection restarts. INT goes
high (high impedance if an external pullup resistor is not
fitted) during the slave acknowledge. The new snapshot
data is the current port data transmitted to the master, and
therefore, port transitions occuring during the transmission
are detected. INT remains high until the STOP condition.
A read from the group B ports of the MAX7326 starts
with the master transmitting the group’s slave address
with the R/W bit set high. The MAX7326 acknowledges
the slave address and samples the logic state of the
output ports during the acknowledge bit. The master
can read one or more bytes from the output ports of the
MAX7326, and then issues a STOP condition (Figure 8).
The MAX7326 transmits the current port data, read
back from the actual port outputs (not the port output
latches) during the acknowledge bit. If a port is forced
to a logic state other than its programmed state, the
readback reflects this. If driving a capacitive load, the
readback port level verification algorithms may need to
take the RC rise/fall time into account.
Typically, the master reads one byte from the group B
ports of the MAX7326, then issues a STOP condition
(Figure 8). However, the master can read two or more
bytes from the output ports of the MAX7326, and then
issues a STOP condition. In this case, the MAX7326
resamples the port outputs during each acknowledge
and transmits the new data each time.
