A remote diode temperature reading register will return a value of 8000h if the remote diode pins are not used by the board
designer or is not functioning properly. This reading will cause the zone limit bits (bits 4 and 6) in the Interrupt Status
Register (41h) and the remote diode fault status bit (bits 6 and 7) in the Interrupt Status Register 2 (42h) to be set. These
registers are read-only – a write to these registers has no effect.
