The period and the duty of 8-bit PWM current source and the state of the SW1 and SW2 switches can be
controlled through the current sharing control register (CSCTRL).
6.4.16 Temperature Reference
The temperature reference register (TEMPREF) provides the ADC12 count when ADC12 measures the
internal temperature sensor (channel 15) during the factory trim and calibration.
This information can be used by different periodic temperature compensation routines implemented in the
firmware. But it should not be overwritten by firmware, otherwise this factory written value will be lost until
the device is reset.
