8.5 Temperature Trip Point registers
While writing to the 16-bit Upper, Lower, or Critical Boundary Alarm Trip registers, please
ensure that both bytes get written before doing a new START or STOP to ensure that a
valid temperature value gets written into the registers.
8.5.1 UPPER Upper Boundary Alarm Trip register (02h, 16-bit read/write)
The value is the upper 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.
