ESCRIPTION
CS
A22
I
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".
N
OTE
:
Internally pulled "High" with a 50k
resistor.

Address Latch Enable Input (Transfer Start)
See the Microprocessor section of this datasheet for a description.

Internally pulled "Low" with a 50k
resistor.

Ready Output (Transfer Acknowledge)
See the Microprocessor section of this datasheet for a description.
INT
B3
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.
N
OTE
:
This pin is an open-drain output that requires an external 10K
pull-up
resistor.
μ
PCLK
AB2
I
Micro Processor Clock Input
In a synchronous microprocessor interface, μPCLK is used as the internal tim-
ing reference for programming the LIU.
N
OTE
:
Internally pulled "Low" with a 50k
resistor.
