The device contains both high and low limits for all temperature channels. If the measured temperature
exceeds the high limit, then the corresponding status bit is set and the ALERT pin is asserted.
Likewise, if the measured temperature is less than or equal to the low limit, the corresponding status
bit is set and the ALERT pin is asserted.
The data format for the limits must match the selected data format for the temperature so that if the
extended temperature range is used, the limits must be programmed in the extended data format.
The limit registers with multiple addresses are fully accessible at either address.
The Scratchpad Registers are Read Write registers that are used for place holders to be software
compatible with legacy programs. Reading from the registers will return what is written to them.
