DSPI Shared IRQ Driver

Overview

This section describes the programming interface of the DSPI shared IRQ driver for master and slave Peripheral drivers.

Functions
void	DSPI_DRV_EdmaIRQHandler (uint32_t instance)
	The function DSPI_DRV_EdmaIRQHandler passes IRQ control to either the master or slave driver. More...
void	DSPI_DRV_IRQHandler (uint32_t instance)
	The function DSPI_DRV_IRQHandler passes IRQ control to either the master or slave driver. More...

Variables
SPI_Type *const	g_dspiBase [SPI_INSTANCE_COUNT]
	Table of base pointers for SPI instances. More...
const IRQn_Type	g_dspiIrqId [SPI_INSTANCE_COUNT]
	Table to save DSPI IRQ enumeration numbers defined in the CMSIS header file. More...
SPI_Type *const	g_dspiBase [SPI_INSTANCE_COUNT]
	Table of base pointers for SPI instances. More...
const IRQn_Type	g_dspiIrqId [SPI_INSTANCE_COUNT]

Function Documentation

void DSPI_DRV_EdmaIRQHandler

(

uint32_t

instance

)

The address of the IRQ handlers are checked to make sure they are non-zero before they are called. If the IRQ handler's address is zero, it means that driver was not present in the link (because the IRQ handlers are marked as weak). This would actually be a program error, because it means the master/slave config for the IRQ was set incorrectly.

Parameters

instance

The instance number of the DSPI peripheral.

void DSPI_DRV_IRQHandler

Parameters

instance

The instance number of the DSPI peripheral.
