The slave updates with the new data.
The master sends a STOP (P) condition.
A bus master initiates communication with a slave
device (MAX8649/MAX8649A) by issuing a START (S)
condition followed by the slave address (the slave
address byte consists of 7 address bits (1100 000x for
MAX8649; 1100 010x for MAX8649A) and a read/write
bit (R/ W )). After receiving the proper address, the ICs
issues an acknowledge by pulling SDA low during the
ninth clock cycle.
The ICs provide different I 2 C slave addresses, allowing
up to two devices to be used in a system without caus-
ing bus collisions. Contact the factory for availability.
Write Operations
The ICs recognize the write byte protocol as defined in
the SMBus specification and shown in Figures 14a and
14b. The write byte protocol allows the I 2 C master device
to send 1 byte of data to the slave device. The write byte
protocol requires a register pointer address for the sub-
sequent write. The ICs acknowledge any register pointer
In addition to the write-byte protocol, the ICs can write to
multiple registers as shown in Figure 14b. This protocol
allows the I 2 C master device to address the slave only
once and then send data to a sequential block of regis-
ters starting at the specified register pointer.
Use the following procedure to write to a sequential
block of registers:
1) The master sends a start command.
2) The master sends the 7-bit slave address followed
by a write bit.
3) The addressed slave asserts an acknowledge by
pulling SDA low.
4) The master sends the 8-bit register pointer of the
first register to write.
5) The slave acknowledges the register pointer.
6) The master sends a data byte.
even though only a subset of those registers actually
exists in the device. The write byte protocol is as follows:
1) The master sends a start command.
7)
8)
9)
The slave acknowledges the data byte.
The slave updates with the new data.
Steps 6 to 8 are repeated for as many registers in

the block, with the register pointer automatically
incremented each time.
