Data Sheet
DATA TRANSFER
Format Overview
The PMBus slave follows the transfer protocol of the SMBus
specification, which is based on the fundamental transfer
protocol format of the Philips I 2 C Bus Specification , dated
January 2000. Data transfers are byte wide, lower byte first.
Each byte is transmitted serially, most significant bit (MSB)
first. A typical transfer is diagrammed in Figure 35. See the
SMBus and I 2 C specifications for an in-depth discussion of
the transfer protocols.
ADP1047/ADP1048
“A” represents the ACK (acknowledge) bit. The ACK bit is typi-
cally active low (Logic 0) if the transmitted byte is successfully
received by a device. However, when the receiving device is the
bus master, the acknowledge bit for the last byte read is a Logic 1,
indicated by A.
Command Overview
Data transfer using the PMBus slave is established using PMBus
commands. The PMBus specification requires that all PMBus
commands start with a slave address with the R/W bit cleared
(set to 0), followed by the command code. All PMBus commands

supported by the ADP1047 / ADP1048 follow one of the protocol

Figure 35. Basic Data Transfer
Figure 35 through Figure 42 use the following abbreviations:
S = start condition
Sr = repeated start condition
P = stop condition
R = read bit
W = write bit
A = acknowledge bit (0)
A = acknowledge bit (1)
The PMBus slave module also supports manufacturer-specific
extended commands. These commands follow the same protocol
as the standard PMBus commands. However, the command
code consists of the following two bytes:
? The command code extension, 0xFE
? The extended command code, 0x00 to 0xFF
Using the manufacturer-specific extended commands, the
PMBus device manufacturer can add an additional 256
manufacturer-specific commands to its PMBus command set.
