DESCRIPTION
CS

Chip Select Input
Active low signal. This signal enables the microprocessor interface by pulling
chip select "Low". The microprocessor interface is disabled when the chip
select signal returns "High".

Read Strobe Input (Write Enable)
See the Microprocessor section of this datasheet for a description.

Ready Output (Transfer Acknowledge)
See the Microprocessor section of this datasheet for a description.
INT

O
Interrupt Output
Active low signal. This signal is asserted "Low" when a change in alarm status
occurs. Once the status registers have been read, the interrupt pin will return
"High". GIE (Global Interrupt Enable) must be set "High" in the appropriate
global register to enable interrupt generation.
NOTE: This pin is an open-drain output that requires an external 10K
pull-up
resistor.
PCLK
AB2

Micro Processor Clock Input
In a synchronous microprocessor interface, PCLK is used as the internal tim-
ing reference for programming the LIU.

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
