Note that the motion during the execution of this test can lead

to false failure results because the self test is designed to detect

changes caused by the internal stimulus only.

Factory Restore

Use the following DIN sequence to set Register GLOB_CMD, Bit

1 = 1: 0xE802, then 0xE900. This command restores the facto-

ry default settings for the MSC_CTRL, DEC_RATE, UP_SCALE,

FIFO_CTRL, FILT_CTRL, and NULL_CTRL registers and clears all

user-configurable bias correction settings.

Executing this command also writes 0x0000 to the following

bias registers: XG_BIAS_LWR, XG_BIAS_UPR, YG_BIAS_LWR,

YG_BIAS_UPR, ZG_BIAS_LWR, ZG_BIAS_UPR, XA_BIAS_LWR,

XA_BIAS_UPR, YA_BIAS_LWR, YA_BIAS_UPR, ZA_BIAS_LWR,

and ZA_BIAS_UPR. Additionally, this command resets the control

registers to their default values, as specified in the default value

column in the corresponding register tables.

The factory restore command also automatically triggers a flash

memory update, ensuring that the restored default settings persist

through subsequent resets.

Bias Correction Update

Use the following DIN pin sequence to set Register GLOB_CMD,

Bit 0 = 1, to trigger a bias correction, using the correction factors

from the CBE (see Table 126): 0xE801, then 0xE900.

Firmware revision, binary coded decimal (BCD) format

The FW_REV register (see Table 129 and Table 130) provides the

firmware revision for the internal firmware. This register uses a

BCD format, where each nibble represents a digit. For example, if

FW_REV = 0x0104, the firmware revision is 1.04.

Factory calibration day, BCD format

The FIRM_DM register (see Table 131 and Table 132) contains the

month and day of the factory calibration date. The DAY_MONTH

month. For example, November is the 11th month in a year and is

represented by the DAY_MONTH register, Bits[15:8] = 0x11. The

DAY_MONTH register, Bits[7:0], contain the day of the factory con-

figuration. For example, the 27th day of the month is represented by

the DAY_MONTH register, Bits[7:0] = 0x27.

The FIRM_YEAR register (see Table 133 and Table 134) contains

the year of the factory calibration in BCD format. For example, the

year 2023 is represented by the FIRM_YEAR register, Bits[15:0] =

0x2023.
