ALARMS
There are four independent alarms, which provide trigger level
and polarity controls. The ALM_CTRL register (Table 38) provides
individual settings for data source selection (Bits[7:4]), static and
dynamic comparison (Bits[14:12]), trigger direction/polarity
(Bits[11:8]), and alarm enable (Bits[3:0]).

SYSTEM ALARM
The system alarm monitors either power supply or internal tem-
perature, according to the user selections in ALM_CTRL[11],
ALM_CTRL[7], ALM_CTRL[3], and the ALM_MAG_S register in
Table 42. For example, set ALM_CTRL = 0x0008 (DIN = 0xA900,
0xA808) and ALM_MAG_S = 0x533 (DIN = 0xA705, 0xA633)
to disable all three inertial alarms and configure the system alarm
active when TEMP_OUT < 0°C.
STATIC ALARMS
The static alarm setting enables the ADIS16210 to compare the
data source (ALM_CTRL[6:4]) with the corresponding values

in the ALM_MAG_x registers (Table 39, Table 40, and Table 41)
using the trigger direction/polarity settings in ALM_CTRL[10:8].
For example, if ALM_CTRL[10] = 0, ALM_CTRL[6] = 1, and
ALM_MAG_Z = 0x2000, then Alarm Z becomes active when
ZINCL_OUT is less than 0x2000, or 45°.
DYNAMIC ALARMS
The dynamic alarm setting monitors the data selection for a
rate-of-change comparison. The rate-of-change comparison is
represented by the magnitude in the ALM_MAG_x registers
(Table 39, Table 40, and Table 41), divided by the time in the
ALM_SMPL_x registers (Table 43, Table 44, Table 45).
For example, if ALM_CTRL[9] = 1, ALM_CTRL[5] = 0,
ALM_MAG_Y = 0x4000, and ALM_SMPL_Y = 0x0064, then
Alarm Y (DIAG_STAT[9]) becomes active when YACCL_OUT
changes by more than +1 g over 100 samples. The AVG_CNT
register (Table 22) establishes the time for each sample.

ALARM REPORTING
See DIAG_STAT[11:8] (Table 36) for alarm flags, which equal 1
when an alarm condition is detected. DIO_CTRL (Table 30)
offers settings that configure DIO1 or DIO2 as an alarm
indicator signal.
