If a voltage input either exceeds the value set in the voltage high limit register or falls below the value set in the voltage low limit
register, the corresponding bit will be set automatically by the LM85 in the interrupt status registers (41-42h). Voltages are
presented in the registers at 34 full scale for the nominal voltage, meaning that at nominal voltage, each input will be C0h, as
shown in Table 2.
Setting the Ready/Lock/Start/Override register Lock bit has no effect on these registers.

If an external temperature input or the internal temperature sensor either exceeds the value set in the corresponding high limit
register or falls below the value set in the corresponding low limit register, the corresponding bit will be set automatically by the
LM85 in the Interrupt Status Register 1 (41h). For example, if the temperature read from the Remote1 and Remote1+ inputs
exceeds the Processor (Zone1) High Temp register limit setting, Interrupt Status Register 1 ZN1 bit will be set. The temperature
limits in these registers are represented as 8 bit, 2’s complement, signed numbers in Celsius, as shown below in Table 3.
Setting the Ready/Lock/Start/Override register Lock bit has no effect on these registers.
