//! \brief Initializes the ADC Module.
//!
//! This function initializes the ADC module to allow for analog-to-digital
//! conversions. Specifically this function sets up the sample-and-hold signal
//! and clock sources for the ADC core to use for conversions. Upon successful
//! completion of the initialization all of the ADC control registers will be
//! reset, excluding the memory controls and reference module bits, the given
//! parameters will be set, and the ADC core will be turned on (Note, that the
//! ADC core only draws power during conversions and remains off when not
//! converting).Note that sample/hold signal sources are device dependent. Note
//! that if re-initializing the ADC after starting a conversion with the
//! startConversion() function, the disableConversion() must be called BEFORE
//! this function can be called.
//!
//! \param baseAddress is the base address of the ADC module.
//! \param sampleHoldSignalSourceSelect is the signal that will trigger a
//! sample-and-hold for an input signal to be converted. This parameter
//! is device specific and sources should be found in the device's
//! datasheet.
//! Valid values are:

//! - \b MPY32_WRITEDELAY_32BIT - writes are delayed until a 32-bit
//! result is available in the result registers
//! - \b MPY32_WRITEDELAY_64BIT - writes are delayed until a 64-bit

//! \brief Gets TLV Info
//!
//! The TLV structure uses a tag or base address to identify segments of the
//! table where information is stored. Some examples of TLV tags are Peripheral
//! Descriptor, Interrupts, Info Block and Die Record. This function retrieves
//! the value of a tag and the length of the tag.
//!
//! \param tag represents the tag for which the information needs to be
//! retrieved.
//! Valid values are:
//! - \b TLV_TAG_LDTAG
//! - \b TLV_TAG_PDTAG
//! - \b TLV_TAG_Reserved3
//! - \b TLV_TAG_Reserved4
//! - \b TLV_TAG_BLANK
//! - \b TLV_TAG_Reserved6
//! - \b TLV_TAG_Reserved7

//! - \b TLV_TAG_ADC12CAL
//! - \b TLV_TAG_ADC10CAL
//! - \b TLV_TAG_REFCAL
//! - \b TLV_TAG_CTSD16CAL
//! \param instance In some cases a specific tag may have more than one
//! instance. For example there may be multiple instances of timer
//! calibration data present under a single Timer Cal tag. This variable
//! specifies the instance for which information is to be retrieved (0,
//! 1, etc.). When only one instance exists; 0 is passed.
//! \param length Acts as a return through indirect reference. The function
//! retrieves the value of the TLV tag length. This value is pointed to
//! by *length and can be used by the application level once the
//! function is called. If the specified tag is not found then the
//! pointer is null 0.
//! \param data_address acts as a return through indirect reference. Once the
//! function is called data_address points to the pointer that holds the
//! value retrieved from the specified TLV tag. If the specified tag is
//! not found then the pointer is null 0.
//!
//! \return None

//! The Peripheral Descriptor tag is split into two portions a list of the

//! This function is used to parse through the first portion and calculate the
//! total flash memory available in a device. The typical usage is to call the
//! TLV_getMemory which returns a non-zero value until the entire memory list
//! has been parsed. When a zero is returned, it indicates that all the memory
//! blocks have been counted and the next address holds the beginning of the
//! device peripheral list.
//!
//! \param instance In some cases a specific tag may have more than one
//! instance. This variable specifies the instance for which information
//! is to be retrieved (0, 1 etc). When only one instance exists; 0 is
//! passed.
