The single slave configuration for the 16-bit module is written.
This command must be repeated for all 31 A-slaves and all 31 B-slaves. If you
don't connect a slave to an address, write F
hex
for ID, IO, ID1, ID2.
3. Write new list of projected slaves
Write the complete LPS of your AS-i circuit.
Every bit in the LPS corresponds to one slave after the following scheme:
Byte0/Bit 0:slave 0/0A - can not be set!
Byte1/Bit 1:slave 1/1A
...
Byte3/Bit 7:slave 31/31A
Byte4/Bit 0:slave 0B - can not be set!
Byte4/Bit 1:slave 1B
...
Byte7/Bit 7:slave 31B
The slave is projected if the bit is set.
Example above: 16-bit module at address 4 ⇒ Set bit 4/byte 0:
No result because toggle bit = 0.
