27 / 36 page Data Sheet ADIS16488 Rev. B | Page 27 of 36 ALARMS Each sensor has an independent alarm function that provides controls for alarm magnitude, polarity, and enabling a dynamic rate-of-change option. The ALM_STS register (see Table 49) contains the alarm output flags and the FNCTIO_CTRL register (see Table 117) provides an option for configuring one of the digital I/O lines as an alarm indicator. STATIC ALARM USE The static alarm setting compares each sensor’s output with the trigger settings in the xx_ALM_MAGN registers (see Table 100, Table 101, Table 102, Table 103, Table 104, Table 105, Table 106, Table 107, Table 108, and Table 109) of that sensor. The polarity controls for each alarm are in the ALM_CNFG_x registers (see Table 110, Table 111, Table 112). The polarity establishes whether greater than or less than produces an alarm condition. The comparison between the xx_ALM_MAGN value and the output data only applies to the upper word or 16 bits of the output data. DYNAMIC ALARM USE The dynamic alarm setting provides the option of comparing the change in each sensor’s output over a period of 48.7 ms with that sensor’s xx_ALM_MAGN register. Table 100.
