SE98A
DDR memory module temp sensor, 1.7 V to 3.6 V
8.5  Temperature Trip Point registers
8.5.1   Upper Boundary Alarm Trip register (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.
