REGISTER DEFINITIONS
NOTE: To write to the registers the MODE bit in the MODE (0x07) register must be set to 0, placing the device in Standby Mode.
$00: 6-bits output value X (Read Only when not in Test Mode)
XOUT — X Output
Signed byte 6-bit 2’s complement data with allowable range of +31 to -32.
XOUT[5] is 0 if the g direction is positive, 1 if the g direction is negative.
If the Alert bit is set, the register was read at the same time as the device was attempting to update the contents. The register
must be read again.
$01: 6-bits output value Y (Read Only when not in Test Mode)
YOUT — Y Output
Signed byte 6-bit 2’s complement data with allowable range of +31 to -32.
YOUT[5] is 0 if the g direction is positive, 1 if the g direction is negative.
If the Alert bit is set, the register was read at the same time as the device was attempting to update the contents. The register
must be read again.
$02: 6-bits output value Z (Read Only when not in Test Mode)
ZOUT — Z Output
Signed byte 6-bit 2’s complement data with allowable range of +31 to -32.
ZOUT[5] is 0 if the g direction is positive, 1 if the g direction is negative.
If the Alert bit is set, the register was read at the same time as the device was attempting to update the contents. The register
must be read again.
