ADM1063
The device also has several identification registers (read-only)
that can be read across the SMBus. Table 12 lists these registers
with their values and functions.
Table 12. Identification Register Values and Functions
All other devices on the bus remain idle while the selected device
waits for data to be read from or written to it. If the R/W bit is a 0,
the master writes to the slave device. If the R/W bit is a 1, the
master reads from the slave device.

Step 2
Data is sent over the serial bus in sequences of nine clock pulses:
eight bits of data followed by an acknowledge bit from the slave
device. Data transitions on the data line must occur during the low
period of the clock signal and remain stable during the high period
General SMBus Timing
general read and write operations using the SMBus. The SMBus
specification defines specific conditions for different types of
read and write operations, which are discussed in the Write
Operations and Read Operations sections.
The general SMBus protocol operates as follows:
Step 1
The master initiates data transfer by establishing a start condition,
defined as a high-to-low transition on the serial data-line SDA
while the serial clock-line SCL remains high. This indicates that
a data stream follows. All slave peripherals connected to the serial
bus respond to the start condition and shift in the next eight bits,
consisting of a 7-bit slave address (MSB first) plus an R/W bit.
This bit determines the direction of the data transfer, that is,
whether data is written to or read from the slave device (0 = write,
1 = read).
The peripheral whose address corresponds to the transmitted
address responds by pulling the data line low during the low
period before the ninth clock pulse, known as the acknowledge
bit, and by holding it low during the high period of this clock pulse.
because a low-to-high transition when the clock is high could be
interpreted as a stop signal. If the operation is a write operation,
the first data byte after the slave address is a command byte. This
command byte tells the slave device what to expect next. It may be
an instruction telling the slave device to expect a block write, or
it may be a register address that tells the slave where subsequent
data is to be written. Because data can flow in only one direction,
as defined by the R/W bit, sending a command to a slave device
during a read operation is not possible. Before a read operation,
it may be necessary to perform a write operation to tell the slave
what sort of read operation to expect and/or the address from
which data is to be read.
Step 3
When all data bytes have been read or written, stop conditions
are established. In write mode, the master pulls the data line high
during the 10th clock pulse to assert a stop condition. In read
mode, the master device releases the SDA line during the low
period before the ninth clock pulse, but the slave device does
not pull it low. This is known as a no acknowledge. The master
then takes the data line low during the low period before the
10th clock pulse and then high during the 10th clock pulse to
assert a stop condition.
