This command allows a register in a specific device
within the SMBus ladder to be written. It is similar to the
WRITEALL command except that the I
contains the fixed MSbs 0b10, followed by the device
address A[0:4] encoded LSB first instead of the broad-
cast address. Once again, a consistent PEC must be
received for the command to be executed by the device.
The PEC alert is set if the command was aborted. The
command sequence is forwarded up the SMBus ladder
until the device address sent with the command match-

es or exceeds the receiving device’s address. If the
addresses match, the device executes the command.
If the command address exceeds the device’s address,
the command forwarding stops. This can happen if
the device addresses assigned during the HELLOALL
command exceeded 0x1F, or if the device addressed
by the WRITEDEVICE command is no longer active.

where the device address matches IC3.
