Functions
Ecode_t	UARTDRV_Abort (UARTDRV_Handle_t handle, UARTDRV_AbortType_t type)
	Abort ongoing UART transfers. More...
Ecode_t	UARTDRV_DeInit (UARTDRV_Handle_t handle)
	Deinitialize a UART driver instance. More...
UARTDRV_FlowControlState_t	UARTDRV_FlowControlGetPeerStatus (UARTDRV_Handle_t handle)
	Checks the peer's flow control status. More...
UARTDRV_FlowControlState_t	UARTDRV_FlowControlGetSelfStatus (UARTDRV_Handle_t handle)
	Checks the self's flow control status. More...
Ecode_t	UARTDRV_FlowControlIgnoreRestrain (UARTDRV_Handle_t handle)
	Enables transmission when restrained by flow control. More...
Ecode_t	UARTDRV_FlowControlSet (UARTDRV_Handle_t handle, UARTDRV_FlowControlState_t state)
	Set UART flow control state. Set nRTS pin if hardware flow control is enabled. Send XON/XOFF if software flow control is enabled. More...
Ecode_t	UARTDRV_FlowControlSetPeerStatus (UARTDRV_Handle_t handle, UARTDRV_FlowControlState_t state)
	Set peer UART flow control state. Pause/resume transmit accordingly. Only for manual software flow control. More...
UARTDRV_Count_t	UARTDRV_ForceReceive (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t maxCount)
	Direct receive without interrupts or callback. Blocking function. More...
Ecode_t	UARTDRV_ForceTransmit (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count)
	Direct transmit without interrupts or callback. Blocking function that ignores flow control if enabled. More...
UARTDRV_Status_t	UARTDRV_GetPeripheralStatus (UARTDRV_Handle_t handle)
	Returns the status of the UART peripheral associated with a given handle. More...
uint8_t	UARTDRV_GetReceiveDepth (UARTDRV_Handle_t handle)
	Returns the number of queued receive operations. More...
UARTDRV_Status_t	UARTDRV_GetReceiveStatus (UARTDRV_Handle_t handle, uint8_t **buffer, UARTDRV_Count_t *itemsReceived, UARTDRV_Count_t *itemsRemaining)
	Check the status of the UART and gather information about any ongoing receive operations. More...
uint8_t	UARTDRV_GetTransmitDepth (UARTDRV_Handle_t handle)

Ecode_t	UARTDRV_PauseTransmit (UARTDRV_Handle_t handle)
	Pause an ongoing transmit operation. More...
Ecode_t	UARTDRV_Receive (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count, UARTDRV_Callback_t callback)
	Start a non-blocking receive. More...
Ecode_t	UARTDRV_ReceiveB (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count)
	Start a blocking receive. More...
Ecode_t	UARTDRV_ResumeTransmit (UARTDRV_Handle_t handle)
	Resume a paused transmit operation. More...
Ecode_t	UARTDRV_Transmit (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count, UARTDRV_Callback_t callback)
	Start a non-blocking transmit. More...
Ecode_t	UARTDRV_TransmitB (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count)
	Start a blocking transmit. More...
