Reading from the MAX7322
A read from the MAX7322 starts with the master trans-
mitting the MAX7322’s slave address with the R/W bit
set high. The MAX7322 acknowledges the slave
address, and samples the ports during the acknowl-
edge bit. INT deasserts during the slave address
acknowledge.
Typically, the master reads one or two bytes from the
MAX7322, each byte being acknowledged by the mas-
ter upon reception with the exception of the last byte.
When the master reads one byte from the MAX7322
and subsequently issues a STOP condition (Figure 6),
the MAX7322 transmits the current port data, clears the
change flags, and restarts the transition detection. INT
deasserts during the slave address acknowledge. The
new snapshot data is the current input port data trans-
mitted to the master, so any input port changes that
occur during the transmission are detected. INT
remains high until the STOP condition.
The master can read two bytes from the MAX7322 and
then issue a STOP condition (Figure 7). In this case, the
MAX7322 transmits the current port data, followed by
the change flags. The change flags are then cleared,
and transition detection restarts. INT deasserts during
the slave address acknowledge. The new snapshot
