Temperature Reference
The temperature reference register (TEMPREF) provides the ADC12 count when ADC12 measured the
internal temperature sensor 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.

Power Disable Control or (Clock Gating Control)
Power Disable Control register provides control bits that can enable or disable arrival of clock to several
peripherals such as, PCM, CPCC, digital filters, front ends, DPWMs, UARTs, ADC-12 and more.
All these controls are enabled as default. If a specific peripheral is not used in a specific application the
clock gate can be disabled in order to block the propagation of clock signal to that peripheral and therefore
reduce the overall current consumption of the device. Please refer to
and Section 3.7 of
UCD3138 device datasheet for more information.
