DSI COMMANDS AND RESPONSES
INITIALIZATION COMMAND
The Initialization command must be sent to the 33793
before it may commence communications over the bus. The
command may be used three ways. The first is to initialize a
programmable address device. The second is the first step in
assigning a pre-programmed address. The third is to initialize
a pre-programmed device.
For the first case this command is sent to address zero
with the NV bit set to zero. The command will be received by
the next daisy chain device with its bus switch open.
Reception of this command will assign the device address
and group number.
For the second case the Initialization command is sent the
same as the first except that the NV bit is set to one.
Reception of the command will assign the device address
and group number. A Read/Write NVM command then may
be sent to complete the setting of a pre-programmed
address.
A pre-programmed device must be initialized by putting its
address in both PA3:PA0 and A3:A0 fields.
Once a device has received an initialization command, it
will ignore further initialization commands unless it has
received a Clear command or undergone a power-up reset.
If BS = 1 and no faults are detected, initialization will cause
the bus switch to close.
The command format is found in

Legend
B[7:0] = 8-bit A/D value.
BS = Status of the Bus Switch (1 = close).
LO = Logic Out level at the Logic Out pin.
IO[3:0] = Logic level of I/O.
NV = Allows nonvolatile address programming if set to “1”.
PA[3:0] = Bus Address to set the device to.
U = Undervoltage Flag.
V[2:0] = Version number.
