Slave Address
The MAX7322 has a 7-bit-long slave address (Figure 5).
The eighth bit following the 7-bit slave address is the R/W
bit. It is low for a write command, and high for a read
command.
The first (A6), second (A5), and third (A4) bits of the
MAX7322 slave address are always 1, 1, and 0.
Connect AD2 and AD0 to GND, V+, SDA, or SCL to
select slave address bits A3, A2, A1, and A0. The
MAX7322 has 16 possible slave addresses (Table 2),
allowing up to 16 MAX7322 devices on an I2C bus.
Accessing the MAX7322
The MAX7322 is accessed through an I2C interface.
The transition flags are cleared, and INT is deasserted
each time the device acknowledges the I2C slave
address.
A single-byte read from the MAX7322 returns the sta-
tus of the four input ports and the four output ports
(read back as inputs).
A 2-byte read returns the status of the four input ports
and the four output ports (as for a single-byte read), fol-
lowed by the transition flags for the four input ports.
A multibyte read (more than 2 bytes before the I2C
STOP bit) repeatedly returns the port data, alternating
with the transition flags. As the data is resampled for
each transmission, and the transition flags are reset
each time, a multibyte read continuously returns the
current data and identifies any changing ports.
If a port data change occurs during the read sequence,
INT is reasserted after the I2C STOP bit. The MAX7322
does not generate another interrupt during a single-
byte or multibyte read.
Port data is sampled during the preceding I2C
acknowledge bit (the acknowledge bit for the I2C slave
address in the case of a single-byte or 2-byte read).
A single-byte write to the MAX7322 sets the logic state
of the four output ports and the 4-bit interrupt mask
resistor, and clears both the internal transition flags and
the INT output when the device acknowledges the
slave address byte.
A multibyte write to the MAX7322 repeatedly sets the
logic state of the four output ports and the 4-bit inter-
rupt mask register.
