Status/Alarm Indicators
The SYS_E_FLAG register in Table 41 provides the system
error flags.
Table 41. SYS_E_FLAG (Page 0, Base Address = 0x08)
Bits Description
[15] Watch dog timer flag (1 = timed out)
[14:8] Not used
[7] Processing overrun (1 = error)
[6] Flash memory (1 = failure)
[5] Inertial self test failure (1= DIAG_STS ≠ 0x00)
[4] Sensor overrange (1 = at least one sensor overranged)
[3] SPI communication error
[2:1] Not used
[0] Alarm status flag (1 = ALM_STS ≠ 0x00)
The DIAG_STS register in Table 42 provides the flags for the
internal self test function.

[2] Self test failure, Z-axis gyroscope (1 = failure)
[1] Self test failure, Y-axis gyroscope (1 = failure)
[0] Self test failure, X-axis gyroscope (1 = failure)
The ALM_STS register in Table 43 provides the alarm bits for
each sensor’s programmable alarm levels.
