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 affect.
The THERM Limit Registers are used to determine whether a critical thermal event has occurred. If
the measured temperature exceeds the THERM Limit, then the THERM pin is asserted. The limit
setting must match the chosen data format of the temperature reading registers.
Unlike the ALERT pin, the THERM pin cannot be masked. Additionally, the THERM pin will be released
once the temperature drops below the corresponding threshold minus the THERM Hysteresis.
The External Diode Fault Register indicates which of the external diodes caused the FAULT bit in the
Status Register to be set. This register is cleared when it is read.
