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.

Writing to this register initiates a single conversion cycle. Data

The One Shot Register is used to initiate a one shot command. Writing to the one shot register when  
the device is in standby mode and BUSY bit (in Status Register) is ‘0’, will immediately cause the ADC  
to update all temperature measurements. Writing to the One Shot Register while the device is in active  
mode will have no effect.

The Therm Limit Registers are used to determine whether a critical thermal event has occurred. If the  
measured temperature exceeds the Therm Limit, the THERM pin is asserted. The limit setting must  
match the chosen data format of the temperature reading registers.
