8.5.2   LOWER  Lower Boundary Alarm Trip register (03h, 16-bit read/write)
The value is the lower threshold temperature value for Alarm mode. The data format is
2s complement with bit 2 = 0.25 癈. 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.
 
 
8.5.3   CRITICAL  Critical Alarm Trip register (04h, 16-bit read/write)
The value is the critical temperature. The data format is 2s complement with
bit 2 = 0.25 癈. RFU bits will always report zero.
