Address Bus Input
ADDR[10:8] is used as a chip select decoder. The LIU has 5 chip select output
pins for enabling up to 5 additional devices for accessing internal registers.
The LIU has the option to select itself (master device), up to 5 additional
devices, or all 6 devices simultaneously by setting the ADDR[10:8] pins speci-
fied below. ADDR[7:0] is a direct address bus for permitting access to the
internal registers.
ADDR[10:8]
000 = Master Device
001 = Chip Select Output 1 (Pin B21)
010 = Chip Select Output 2 (Pin D19)
011 = Chip Select Output 3 (Pin C20)
100 = Chip Select Output 4 (Pin A21)
101 = Chip Select Output 5 (Pin B20)
110 = Reserved
111 = All Chip Selects Active Including the Master Device

Chip Select Output
The XRT83VSH314 can be used to provide the necessary chip selects for up
to 5 additional devices by using the 3 MSBs ADDR[10:8] from the 11-Bit
address bus. The LIU allows up to 84-channel applications with only using one
chip select. See the ADDR[10:0] definition in the pin description.
