For RTOLB: Remote Temperature Offset High Byte. Power-on default is 0C. 1 LSB = 0.125C. Two’s complement format.
The offset value written to these registers will automatically be added to or subtracted from the remote temperature measurement
that will be reported in the Remote Temperature registers.

D7–D0: T_CRIT setpoint temperature data. Local power-on default is T_CRIT = 85C. Remote power-on default is T_CRIT =
110C (+126C actual remote diode temperature). 1 LSB = 1C, two’s complement format.

2.12 MANUFACTURERS ID REGISTER
(Read Address FEh) Default value 01h.
2.13 DIE REVISION CODE REGISTER
(Read Address FFh) The LM99 version has a default value 31h or 49 decimal. The LM99-1 version has a default value of 34h or
52 decimal. This register will increment by 1 every time there is a revision to the die by National Semiconductor.
