Chip Select Decoder Input Pins [2:0]
CSdec[2:0] are used as a chip select decoder. The LIU has 5 chip select out-
put 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 CSdec[2:0] pins speci-
fied below.
000 = Master Device
001 = Chip Select Output 1
010 = Chip Select Output 2
011 = Chip Select Output 3
100 = Chip Select Output 4
101 = Chip Select Output 5
110 = Reserved
111 = All Chip Selects Active Including the Master Device
Internally pulled "Low" with a 50k
resistor.

Chip Select Output
The XRT83VSH316 can be used to provide the necessary chip selects for up
to 5 additional devices by using the CSdec[2:0] input pins. The LIU allows up
to 84-channel applications with only using one chip select. See the CSdec[2:0]
definition in the pin description.

General Purpose Input/Output
These two GPIO pins are controlled through the internal registers in the micro-
processor block. One register controls the direction, while the other register is
used to store or retrieve the status of these pins.
