MAX9611/MAX9612

Slave Address
A bus master initiates communication with a slave
device by issuing a START (S) condition followed by a
slave address. When idle, the MAX9611/MAX9612 con-
tinuously wait for a START condition followed by their
slave address. When the MAX9611/MAX9612 recognize
a slave address, it is ready to accept or send data. The
MAX9611/MAX9612 offer 16 different slave addresses
using two address inputs, A1 and A0. See Table 2 for
different slave address options. The least significant bit
(LSB) of the address byte (R/W) determines whether
the master is writing to or reading from the MAX9611/
MAX9612 (R/W = 0 selects a write condition, R/W = 1
selects a read condition). After receiving the address,
the MAX9611/MAX9612 (slave) issue an acknowledge
by pulling SDA low for one clock cycle.
I2C Write Operation
A write operation (Figure 1) begins with the bus master
issuing a START condition followed by seven address
bits and a write bit (R/W = 0). If the address byte is
successfully received, the MAX9611/MAX9612 (slave)
issue an acknowledge (A). The master then writes to
the slave and the sequence is terminated by a STOP (P)
condition for a single write operation.
For a burst write operation, more data bytes are sent after
the register address before the transaction is terminated.
I2C Read Operation
In an I2C read operation (Figure 2), the bus master
issues a write command first by initiating a START condi-
tion followed by seven address bits, a write bit (R/W = 0)
and the 8-bit register address. The master then issues
a Repeated START (Sr) condition, followed by seven
address bits, a read bit (R/W = 1). If the address byte
is successfully received, the MAX9611/MAX9612 (slave)
issue an acknowledge (A). The master then reads from
the slave. For continuous read, the master issues an
acknowledge bit (AM) after each received byte. The
master terminates the read operation by sending a not
acknowledge (NA) bit. The MAX9611/MAX9612 then
release the data line SDA allowing the master to gener-
ate a STOP condition.
