T13 to T0:

Temperature result. Bits 15 to 2.

The data format is 14 bits, 0.03125°C per LSB in twos complement format. Full scale allows a result of up to ±256°C. Reset value is 00h.

Note:

Writing to the Configuration register will restart the ADC conversion (unless the write is to put the device in shutdown mode)

RST:

Software Reset Bit. Bit 15 (Write Only)

Writing 1 to this bit generates a system reset that is the same as power on reset. It will reset all registers to default values including

configuration register. This bit self-clears. Any conversion in progress is terminated.
