FUNCTIONAL DESCRIPTION
The CS2082 is an automotive air bag deployment and
diagnostic system for up to two independent firing loops.
Communication with the ASIC is through a synchronous
serial port using Serial Peripheral Interface (SPI) protocol,
at CLK rates up to 2.0 MHz.
Data is simultaneously sent from the DOUT pin and
received at the DIN pin under the control of the CS and CLK
pins. Error detection logic is included in the SPI to guard
against glitches on either the CS or CLK logic signal inputs.
A valid CS frame must contain exactly 8 CLK cycles for
each CS low–high–low transition. Detection of a frame error
will cause input data for that frame to be ignored and an error
code ($FE) to be sent during the next valid CS frame.
The data at DOUT is sent MSB first and is guaranteed valid
before the rising edge of CLK. The 8 bits sent from DOUT
after CS goes high will be the previous data received, data
from either the status register or the fault register, or the CS
frame error code ($FE).
The data at DIN is received MSB first and must be valid
before the rising edge of CLK. The 8 bits received at DIN
before CS goes low will be the current command. Table 1
defines the legal 8–bit SPI commands, where d = four data
bits and x = don’t care. All other inputs will be ignored.

Read Status Register – $1x
The $1x command causes the data contained in the status
register to be sent from DOUT during the next valid CS
frame. The status register reports the condition of the firing
paths, closure detection of an external safing switch between
the VRES and VR1 pins, the state of the internal charge
pump, and the state of external VBAT and VRES power
supplies. The status register is an 8–bit active–high register
with bit definition as shown in Table 2.

Read Fault Register – $2x
The $2x command causes the data contained in the fault
register to be sent from DOUT during the next valid CS
frame. The register reports fire path faults by continuously
comparing each path to a portion of the voltage at the VBAT
pin. The fault register is an 8–bit active–high register with
bit definition as shown in Table 3.
