PMBus Power-Supply Data Logger
Group Command
The device supports the group command. With the group
command, a host can write different data to multiple
data stream. All the devices addressed during this trans-
action wait for the host to issue a STOP before beginning
to respond to the command.

Addressing
The device responds to receiving its fixed slave address
by asserting an acknowledge (ACK) on the bus. The
device does not respond to a general call address; it only
responds when it receives its fixed slave address.
Host Sends or Reads Too Few Bits
If for any reason the host does not complete writing a full
byte or reading a full byte from the device before a START
or STOP is received, the device does the following:
1) Ignores the command.
2) Sets the CML bit in STATUS_BYTE.
Maxim Integrated
3) Sets the CML bit in STATUS_WORD.
4) Sets the DATA_FAULT bit in STATUS_CML.
Host Sends or Reads Too Few Bytes
For each supported command, the device expects a
fixed number of bytes to be written or read from the
device. If for any reason fewer than the expected number
of bytes is written to or read from the device, the device
completely ignores the command and takes no action.
Host Sends Too Many Bytes or Bits
For each supported command, the device expects a
fixed number of bytes to be written to the device. If for
