Product data sheet
8.5.1 Upper Boundary Alarm Trip register (16-bit read/write)
8.5 Temperature Trip Point registers
The value is the upper 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.
