Inputs	None
Outputs	None
Returns	Success = SUNI4x622_SUCCESS
	Failure = SUNI4x622_ERR_INVALID_MODULE_STATE
Valid States	SUNI4x622_MOD_IDLE, SUNI4x622_MOD_READY
Side Effects	Changes the MODULE state to SUNI4x622_MOD_START

Starting the Driver Module: suni4x622ModuleStart

This function connects the RTOS resources to the driver. This involves allocating semaphores and timers, initializing buffers and installing the ISR handler and DPR task. Upon successful return from this function the driver is ready to add devices.

Prototype	INT4 suni4x622ModuleStart(void)
Inputs	None
Outputs	None
Returns	Success = SUNI4x622_SUCCESS
	Failure = SUNI4x622_ERR_INVALID_MODULE_STATE
	SUNI4x622_ERR_MEM_ALLOC
	SUNI4x622_ERR_INT_INSTALL
Valid States	SUNI4x622_MOD_IDLE
Side Effects	Changes the MODULE state to SUNI4x622_MOD_READY

Stopping the Driver Module: suni4x622ModuleStop

This function disconnects the RTOS resources from the driver. This involves de-allocating semaphores and timers, freeing-up buffers and uninstalling the ISR handler and the DPR task. If there are any registered devices, suni4x622Delete is called for each.

Prototype	INT4 suni4x622ModuleStop(void)
Inputs	None
Outputs	None
Returns	Success = SUNI4x622_SUCCESS
	Failure = SUNI4x622_ERR_INVALID_MODULE_STATE
Valid States	SUNI4x622_MOD_READY
