Writing to the MAX7324
A write to the input ports of the MAX7324 starts with the
master transmitting the group’s slave address with the
R/W bit set low. The MAX7324 acknowledges the slave
address and samples the ports during the acknowl-
edge bit. INT deasserts during the slave acknowledge.
The master can now transmit one or more bytes of
data. The MAX7324 acknowledges these subsequent
bytes of data and updates the interrupt mask register
with each new byte until the master issues a STOP con-
dition (Figure 9).
A write to the output ports of the MAX7324 starts with
the master transmitting the group’s slave address with
the R/W bit set low. The MAX7324 acknowledges the
slave address and samples the ports during the
acknowledge bit. The master can now transmit one or
more bytes of data. The MAX7324 acknowledges these
subsequent bytes of data and updates the correspond-
ing group’s ports with each new byte until the master
issues a STOP condition (Figure 10).
