    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
    LM96000 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.

    The Fan Tachometer Low Limit registers indicate the tachometer reading under which the corresponding bit will be set in the
    Interrupt Status Register 2 register. In Auto Fan Control mode, the fan can run at low speeds, so care should be taken in software
