Defines
#define	PORTA_PIN(y)   (PORTA|y)
	Some registers and variables require indentifying GPIO by a single number instead of the port and pin.
#define	PORTB_PIN(y)   (PORTB|y)
	Some registers and variables require indentifying GPIO by a single number instead of the port and pin.
#define	PORTC_PIN(y)   (PORTC|y)
	Some registers and variables require indentifying GPIO by a single number instead of the port and pin.
#define	PORTx_PIN(x, y)   (x|y)
	Some registers and variables require indentifying GPIO by a single number instead of the port and pin.
Functions
void	halInternalResetWatchDog (void)
	Resets the watchdog timer.
void	halGpioConfig (int32u io, int32u config)
	Configure an IO pin's operating mode.
void	halGpioSet (int32u io, boolean value)
	Set/Clear single GPIO bit.
void	halInternalCalibrateSlowRc (void)
	Calibrates the internal SlowRC to generate a 1024 Hz (1kHz) clock.
void	halInternalCalibrateFastRc (void)
	Calibrates the internal FastRC to generate a 12Mhz clock.
void	halInternalSetRegTrim (boolean boostMode)
	Sets the trim values for the 1.8V and 1.2V regulators based upon manufacturing configuration.
int16u	stMeasureVddSlow (void)
	Takes a slow ADC measurement of VDD_PADS in millivolts.
int16u	stMeasureVddFast (void)
	Takes a fast ADC measurement of VDD_PADS in millivolts.
void	halCommonCalibratePads (void)
	Calibrates the GPIO pads.
void	halCommonCheckXtalBiasTrim (void)
	This function is intended to be called periodically, from the stack and application, to check the XTAL bias trim is within appropriate levels and adjust if not.
void	halInternalSwitchToXtal (void)
	Switches to running off of the 24MHz crystal, including changing the CPU to be 24MHz (FCLK sourced from SYSCLK).
void	halInternalSearchForBiasTrim (void)
	Search for optimal 24MHz crystal bias trim, assuming no valid prior value.
void	halCommonDelayMilliseconds (int16u ms)
	Blocks the current thread of execution for the specified amount of time, in milliseconds.
void	halSleepWithOptions (SleepModes sleepMode, int32u gpioWakeBitMask)
	Puts the microcontroller to sleep in a specified mode, allows the GPIO wake sources to be determined at runtime.
StStatus	halSleepForQsWithOptions (int32u *duration, int32u gpioWakeBitMask)
	Uses the system timer to enter ::SLEEPMODE_WAKETIMER for approximately the specified amount of time (provided in quarter seconds), the GPIO wake sources can be provided at runtime.
void	halInternalIdleSleep (void)
	Provides access to assembly code which triggers idle sleep.
void	halInternalSleep (SleepModes sleepMode)
	Puts the microcontroller to sleep in a specified mode.
int32u	halGetWakeInfo (void)
	Obtains the events that caused the last wake from sleep.
void	halCommonSeedRandom (int32u seed)
	Seeds the halCommonGetRandom() pseudorandom number generator.
int16u	halCommonGetRandom (void)
	Runs a standard LFSR to generate pseudorandom numbers.
