-======================
-ADC Synchronous driver
-======================
-
-An ADC (Analog-to-Digital Converter) converts analog signals to digital values.
-A reference signal with a known voltage level is quantified into equally
-sized chunks, each representing a digital value from 0 to the highest number
-possible with the bit resolution supported by the ADC. The input voltage
-measured by the ADC is compared against these chunks and the chunk with the
-closest voltage level defines the digital value that can be used to represent
-the analog input voltage level.
-
-Usually an ADC can operate in either differential or single-ended mode.
-In differential mode two signals (V+ and V-) are compared against each other
-and the resulting digital value represents the relative voltage level between
-V+ and V-. This means that if the input voltage level on V+ is lower than on
-V- the digital value is negative, which also means that in differential
-mode one bit is lost to the sign. In single-ended mode only V+ is compared
-against the reference voltage, and the resulting digital value can only be
-positive, but the full bit-range of the ADC can be used.
-
-Usually multiple resolutions are supported by the ADC, lower resolution can
-reduce the conversion time, but lose accuracy.
-
-Some ADCs has a gain stage on the input lines which can be used to increase the
-dynamic range. The default gain value is usually x1, which means that the
-conversion range is from 0V to the reference voltage.
-Applications can change the gain stage, to increase or reduce the conversion
-range.
-
-The window mode allows the conversion result to be compared to a set of
-predefined threshold values. Applications can use callback function to monitor
-if the conversion result exceeds predefined threshold value.
-
-Usually multiple reference voltages are supported by the ADC, both internal and
-external with difference voltage levels. The reference voltage have an impact
-on the accuracy, and should be selected to cover the full range of the analog
-input signal and never less than the expected maximum input voltage.
-
-There are two conversion modes supported by ADC, single shot and free running.
-In single shot mode the ADC only make one conversion when triggered by the
-application, in free running mode it continues to make conversion from it
-is triggered until it is stopped by the application. When window monitoring,
-the ADC should be set to free running mode.

-The PWM Driver(bare-bone)
-=========================
-
-Pulse-width modulation (PWM) is used to create an analog behavior
-digitally by controlling the amount of power transferred to the
-connected peripheral. This is achieved by controlling the high period
-(duty-cycle) of a periodic signal.
-
-User can change the period or duty cycle whenever PWM is running. The
-function pwm_set_parameters is used to configure these two parameters.
-Note these are raw register values and the parameter duty_cycle means
-the period of first half during one cycle, which should be not beyond
-total period value.
-
-In addition, user can also get multi PWM channels output from different
-peripherals at the same time, which is implemented more flexible by the
-function pointers.
-
-Features
---------
-
-* Initialization/de-initialization
-* Enabling/disabling
-* Run-time control of PWM duty-cycle and period
-* Notifications about errors and one PWM cycle is done
-
-Applications
-------------
-
-Motor control, ballast, LED, H-bridge, power converters, and
-other types of power control applications.
-
-Dependencies
-------------
-
-The peripheral which can perform waveform generation like frequency
-generation and pulse-width modulation, such as Timer/Counter.
-
-Concurrency
------------
-
-N/A
-
-Limitations
------------
-
-The current driver doesn't support the features like recoverable,
-non-recoverable faults, dithering, dead-time insertion.
-
-Known issues and workarounds
