Slave Addresses
The MAX7360 has a 7-bit long slave address (Figure
6). The bit following a 7-bit slave address is the R/W bit,
which is low for a write command and high for a read
command.
The first 4 bits (MSBs) of the MAX7360 slave address
are always 0111. Slave address bits A3, A2, and A1
correspond, by the matrix in Table 3, to the states of the
device address input AD0, and A0 corresponds to the
R/W bit. The AD0 input can be connected to any of four
signals (GND, VCC, SDA, or SCL), giving four possible
slave address pairs and allowing up to four MAX7360
devices to share the bus. Because SDA and SCL are
dynamic signals, care must be taken to ensure that AD0
transitions no sooner than the signals on SDA and SCL.
The MAX7360 monitors the bus continuously, waiting for a
START condition, followed by its slave address. When the
MAX7360 recognizes its slave address, it acknowledges
and is then ready for continued communication.
Bus Timeout
The MAX7360 features a 20ms minimum bus timeout
on the 2-wire serial interface, largely to prevent the
MAX7360 from holding the SDA I/O low during a read
transaction should the SCL lock up for any reason before
a serial transaction is completed. Bus timeout operates
by causing the MAX7360 to internally terminate a serial
