Functions
int	Io_Start (int index, bool lock)
	Get access to an IO line, possibly locking it.
int	Io_Stop (int index)
	Release your lock on an IO line, possibly deactivating it.
bool	Io_GetActive (int index)
	Read whether an IO pin is in use.
int	Io_SetDirection (int index, bool output)
	Set whether an IO line is an output or an input.
bool	Io_GetDirection (int index)
	Read whether an IO line is an output or an input.
int	Io_SetValue (int index, bool value)
	Turn an IO line on or off.
bool	Io_GetValue (int index)
	Read whether an IO line, presumably set as an output, is on or off.
int	Io_SetPeripheralA (int index)
	Configure an IO line to be part of its peripheral A.
int	Io_SetPeripheralB (int index)
	Configure an IO line to be part of its peripheral B.
int	Io_SetPio (int index, bool enable)
	Configure an IO line to be a general purpose IO.
bool	Io_GetPio (int index)
	Read whether an IO line is configured as a general purpose IO.
int	Io_SetPullup (int index, bool enable)
	Set the pullup resistor for an IO line on or off.
bool	Io_GetPullup (int index)
	Read whether the pullup resistor for an IO line on or off.
void	Io_SetValueBits (longlong bits, longlong values)
	Set the values of a batch of IO lines at once.
void	Io_SetDirectionBits (longlong bits, bool output)
	Set a batch of IO lines to a particular direction (in or out) at once.
void	Io_SetPioBits (longlong bits, bool enable)
	Set a batch of IO lines to being general IOs at once.
longlong	Io_GetValueBits ()
	Get a bitmask with the output values of all the IO lines.
longlong	Io_GetPullupBits ()
	Get a bitmask with the state of the internal pullup for all the IO lines.
longlong	Io_GetPioBits ()
	Get a bitmask indicating PIO configuration for all the IO lines.
longlong	Io_GetDirectionBits ()
	Get a bitmask indicating the in-or-out configuration for all the IO lines.
