Detailed Description

XMEGA AWeX driver source file.

This file contains the function implementations the XMEGA AWeX driver.

The driver is not intended for size and/or speed critical code, since most functions are just a few lines of code, and the function call overhead would decrease code performance. The driver is intended for rapid prototyping and documentation purposes for getting started with the XMEGA AWeX module.

For size and/or speed critical code, it is recommended to copy the function contents directly into your application instead of making a function call.

Application note:

AVR1311: Using the XMEGA Timer/Counter Extensions.

Function Documentation

AWEX_ConfigureFaultDetection()

void AWEX_ConfigureFaultDetection	(	AWEX_t *	awex,
		AWEX_FDACT_t	faultAction,
		uint8_t	eventMask
	)

This function configures the Fault Detection function for this AWEX.

Parameters

awex	The AWEX module.
faultAction	Action to perform on a fault condition.
eventMask	Mask of event channels that will trigger a Fault.

Definition at line 117 of file awex_driver.c.

{
    awex->FDCTRL = ( awex->FDCTRL & ~AWEX_FDACT_gm ) | faultAction;
    awex->FDEMASK = eventMask;
}

AWEX_DisableDeadTimeInsertion()

void AWEX_DisableDeadTimeInsertion	(	AWEX_t *	awex,
		uint8_t	disableMask
	)

Disable Dead Time Insertion.

This function disables Dead Time Insertion for the channels selected in the disableMask. The disableMask can be obtained by ORing together the symbols

• AWEX_DTICCAEN_bm
• AWEX_DTICCBEN_bm
• AWEX_DTICCCEN_bm
• AWEX_DTICCDEN_bm

Parameters

awex	The AWEX module.
disableMask	Mask of channels to disable.

Definition at line 98 of file awex_driver.c.

{
    /* Make sure only the DTI enable bits are affected. */
    disableMask &= ( AWEX_DTICCAEN_bm |
                     AWEX_DTICCBEN_bm |
                     AWEX_DTICCCEN_bm |
                     AWEX_DTICCDEN_bm );

    /* Disable DTI for the selected channels. */
    awex->CTRL &= ~disableMask;
}

AWEX_EnableDeadTimeInsertion()

void AWEX_EnableDeadTimeInsertion	(	AWEX_t *	awex,
		uint8_t	enableMask
	)

Enable Dead Time Insertion.

This function enables Dead Time Insertion for the channels selected in the enableMask. The enableMask can be obtained by ORing together the symbols

• AWEX_DTICCAEN_bm
• AWEX_DTICCBEN_bm
• AWEX_DTICCCEN_bm
• AWEX_DTICCDEN_bm

Parameters

awex	The AWEX module.
enableMask	Mask of channels to enable.
