The Error Code is a bit pattern defined as 1000 0000
an illegal or undefined SPI command is attempted executed, or if a RARH or RARLX command was executed while
at the same time any one or more of the Status Register flags is a ‘0’. The RARH command accesses the 8 MSBs
of the 12 bit 2’s complement rate data. Negative angular rate data is limited (clamped) to -2032 (binary 1000 0001

otherwise be confused with the Error Code. For symmetry reasons positive angular rate data is likewise limited to
2032. Note that this angular rate data limiting does not affect any Status Register flags.
