 NRFX_SR_VDMA_INST_COND_SET_JOB(_inst, BELLS, FEATURE.BELLS, 0) \
 ) \
 )

Macro for generating a set of jobs for a SPU peripheral.

It skips an instance if there is a define forcing skipping set to 1 (e.g. SPU010_SR_VDMA_SKIP to skip VDMA jobs for SPU010 instance).

Macro attempts to generate jobs for features which are supported by the given instance.

Parameters

[in]	_inst	Instance, e.g. SPU010.
[in]	_with_periph	Set to 1 if PERIPH section shall also be included.

Returns: Job descriptors.

◆ _NRFX_SPU_VDMA_LEN

#define _NRFX_SPU_VDMA_LEN	(	_inst,
		_with_periph
	)

Value:

 NRFX_COND_CODE_1(NRFX_CONCAT(_inst, _SR_VDMA_SKIP), \
 (0), \
 ((NRFX_SR_VDMA_INST_SET_LEN(_inst, INTEN) + \
 NRFX_COND_CODE_1(_with_periph, \
 ((NRFX_CONCAT(_inst, _PERIPH_COUNT) * \
 sizeof(NRF_SPU_PERIPH_Type))), \
 (0)) + \
 NRFX_SR_VDMA_INST_COND_SET_LEN(_inst, IPCT, FEATURE.IPCT) + \
 NRFX_SR_VDMA_INST_COND_SET_LEN(_inst, DPPIC, FEATURE.DPPIC) + \
 NRFX_SR_VDMA_INST_COND_SET_LEN(_inst, GPIOTE, FEATURE.GPIOTE) + \
 NRFX_SR_VDMA_INST_COND_SET_LEN(_inst, GPIO, FEATURE.GPIO) + \
 NRFX_SR_VDMA_INST_COND_SET_LEN(_inst, GRTC, FEATURE.GRTC) + \
 NRFX_SR_VDMA_INST_COND_SET_LEN(_inst, BELLS, FEATURE.BELLS))))

Macro for calculating length of a save & restore transfer for the given SPU instance.

Macro generates a sum of bytes transfered by jobs for a SPU instance. It skips an instance if there is a define forcing skipping set to 1 (e.g. SPU010_SR_VDMA_SKIP to skip VDMA jobs for SPU010 instance).

Macro attempts to sum transfer lengths for jobs for features which are supported by the given instance.

Parameters

[in]	_inst	Instance, e.g. SPU010.
[in]	_with_periph	Set to 1 if PERIPH section should be included.

◆ NRFX_SR_VDMA_SPU_JOB

#define NRFX_SR_VDMA_SPU_JOB ( ) NRFX_FOREACH_PRESENT(SPU, NRFX_INSTANCE_CONCAT, (), (), _NRFX_SPU_VDMA_JOB, 1)

Macro for generating a set of VDMA jobs for transfer engaging all SPU instances.

Instances may be ommited by defining <instance>_SR_VDMA_SKIP to 1.

Returns: Job descriptors.

◆ NRFX_SR_VDMA_SPU_LEN

#define NRFX_SR_VDMA_SPU_LEN ( ) (NRFX_FOREACH_PRESENT(SPU, NRFX_INSTANCE_CONCAT, (+), (0), _NRFX_SPU_VDMA_LEN, 1))

Macro for calculating length of a save & restore transfer for all SPU instances.
