XBARB: Inter-Peripheral Crossbar Switch Driver

Overview

This document consists of sections titled with Driver Overview, Data Structures, Enumerations, Functions, etc., each with an overview list and detailed documentation. It is recommended to read the Driver Overview first for it includes a comprehensive description of the peripheral, driver and driver changes. Other sections give detailed information for APIs, enums, macros, etc., for your further reference.

Macros
#define	XBARB_SELx(base, output)   (((volatile uint16_t *)(&((base)->SEL0)))[(uint8_t)(output) >> 0x01U])
	Macro function to extract the XBAR select register address for a given xbar output signal.
#define	XBARB_SELx_SELn_SHIFT(output)   ((output & 0x01U) ? 8U : 0U)
	Macro function to get SELn field shift in XBARB_SELx register for a given output signal.
#define	XBARB_SELx_SELn_MASK(output)   ((output & 0x01U) ? 0x3F00U : 0x3FU)
	Macro function to get SELn field mask in XBARB_SELx register for a given output signal.
#define	XBARB_SELx_SELn(output, input_signal)   (((uint16_t)(((uint16_t)(input_signal)) << XBARB_SELx_SELn_SHIFT(output))) & XBARB_SELx_SELn_MASK(output))
	Macro function to create SELn field value in XBARB_SELx register for given output signal and input signal value input_signal, see xbar_input_signal_t.

Function Documentation

void XBARB_Init

(

XBARB_Type *

base

)

Reserved function, enable clock preparation.

Parameters

base	XBARB peripheral address.

void XBARB_Deinit

(

XBARB_Type *

base

)

Reserved function, disable clock preparation.

Parameters

base	XBARB peripheral address.

void XBARB_SetSignalsConnection	(	XBARB_Type *	base,
		xbar_input_signal_t	eInput,
		xbar_output_signal_t	eOutput
	)

This function configures which XBARB input is connected to the selected XBARB output. If more than one XBARB module is available, only the inputs and outputs from the same module can be connected.

param base XBARB peripheral address. param eInput XBARB input signal. param eOutput XBARB output signal.
