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
N
Bi-directional Data Bus
DATA[7:0] is a bi-directional data bus used for read and write operations.
N
Microprocessor Type Select Input
µPTS[2:0] are used to select the microprocessor type interface.
000 = Intel 68HC11, 8051, 80C188 (Asynchronous)
001 = Motorola 68K (Asynchronous)
111 = Motorola MPC8260, MPC860 Power PC (Synchronous)
N
Hardware Reset Input
Active low signal. When this pin is pulled "Low" for more than 10µS, the inter-
nal registers are set to their default state. See the register description for the
default values.
N
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.
