Why do I have an option between 13 and 16 bit temperature readings?
In 16-bit mode the user has a resolution of 0.0078°C but in 13-bit mode the
resolution is only 0.0625°C. However in 13-bit mode the 3 LSB’s of the
temperature register also contain the T_High, T_Low and T_Crit register flags.
If an interrupt is triggered it will appear in these bits. This can be useful
in continuous read mode where the master is only inputting a clock to receive a
temperature reading and not continuously polling over limit registers or
monitoring interrupt pins.
