The ID register contains information about the product version and value is loaded from non-
volatile memory. Each VTI Automotive Digital Accelerometer Platform product will have a unique
identification number. Single axis products can be differentiated from multi axis products through
this register.

Description
ASIC revision identification number, each ASIC version
has different REVID-number.
Description
Writing 0C'hex, 05'hex, 0F'hex in this order resets
component.
Description
Component identification number
(write operation by user is possible to this register but
not to non-volatile memory)
STS have same priority and they can be set and
used simultaneously.
This bit is set to 0 when test is over. Use
INT_STATUS.STS and ST bit of SPI frame for test
result monitoring.
0 = Set MISO line to normal state (= High
impedance state between SPI transfers, data out
state during transfers)
1 = Set MISO like to a continuous high impedance
state (same write command to multiple slaves,
which share MISO line).
