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".

Ready Output (Transfer Acknowledge)
See the Microprocessor section of this datasheet for a description.
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
Micro Processor Clock Input
In a synchronous microprocessor interface, µPCLK is used as the internal tim-
ing reference for programming the LIU.
