If the extended resolution bits of these readings are also being read, the extended resolution registers (0x76, 0x77) must be read first. Once the extended resolution
registers have been read, the associated MSB reading registers are frozen until read. Both the extended resolution registers and the MSB registers are frozen.

These temperature readings can be in twos complement or Offset 64 format; this interpretation is determined by Bit 0 of Configuration Register 5 (0x7C).
If the extended resolution bits of these readings are also being read, the extended resolution registers (0x76, 0x77) must be read first. Once the extended resolution
registers have been read, all associated MSB reading registers are frozen until read. Both the extended resolution registers and the MSB registers are frozen.
In twos complement mode, a temperature reading of −128°C (0x80) indicates a diode fault (open or short) on that channel.
In Offset 64 mode, a temperature reading of −64°C (0x00) indicates a diode fault (open or short) on that channel.
