SPI Commands
The three SafeGuard disable commands MUST be issued in the -1,-2,-3 sequence, and with the addresses shown. Any in-
between commands or incorrect addresses will reset the SafeGuard disable sequence. A single SGEN command re-
enables the SafeGuard.
The RARH command latches high and low bytes such that a sequence of RARH first followed by RARLX guarantees bits
from the same Angular rate sample.
In case of a recoverable error condition, issuing this command re-enables continued angular rate readout. Note that for this
command to function the SafeGuard must be disabled. See also chapter 8 for details.
With load of 100pF connected to V
Characteristic is based on proven library I/O cell performance.
By design.
