8.5.2 Lower Boundary Alarm Trip Register (16-bit read/write)
8.5.3 Critical Alarm Trip Register (16-bit read/write)
The value is the lower threshold temperature value for Alarm mode. The data format is
2’s complement with bit 2 = 0.25 C. RFU bits will always report zero. Interrupts will
respond to the presently programmed boundary values. If boundary values are being
altered in-system, it is advised to turn off interrupts until a known state can be obtained to
avoid superfluous interrupt activity.
Table 16.
Table 17.
The value is the critical temperature. The data format is 2’s complement with
bit 2 = 0.25 C. RFU bits will always report zero.
