C Command List
WR
This command sets the device address of the first part in the chain. All
other parts in the chain are then assigned an automatically incremented
address as this command is forwarded from module to module. The
HELLOALL command should be issued after any power cycle or shut-
down event.
Reads 2 bytes from each device in the chain, which includes the
address byte. When 0xFF is returned, the host has the addresses
of all devices. The ROLLCALL command should be issued after the
HELLOALL command.
The host informs all devices of the device count determined by the
ROLLCALL command so that each device can know when to expect
and generate PEC bytes. The SETLASTADDRESS command should be
issued after the ROLLCALL command.
Broadcasts a common command to all enabled devices in the chain.
Reads the available data from the device register specified by the com-
mand code byte for each device in the chain.
Writes data only to a specified target device.
