eDMA transfer size configuration.
This structure configures the basic source/destination transfer attribute. Implements : edma_transfer_config_t_Class
Definition at line 362 of file edma_driver.h.
uint32_t destAddr |
Memory address pointing to the destination data.
Definition at line 364 of file edma_driver.h.
int32_t destLastAddrAdjust |
Last destination address adjustment. Note here it is only valid when scatter/gather feature is not enabled.
Definition at line 374 of file edma_driver.h.
edma_modulo_t destModulo |
Destination address modulo.
Definition at line 377 of file edma_driver.h.
int16_t destOffset |
Sign-extended offset applied to the current destination address to form the next-state value as each source read/write is completed.
Definition at line 370 of file edma_driver.h.
edma_transfer_size_t destTransferSize |
Destination data transfer size.
Definition at line 366 of file edma_driver.h.
bool interruptEnable |
Enable the interrupt request when the major loop count completes
Definition at line 385 of file edma_driver.h.
edma_loop_transfer_config_t* loopTransferConfig |
Pointer to loop transfer configuration structure (defines minor/major loop attributes) Note: this field is only used when minor loop mapping is enabled from DMA configuration.
Definition at line 387 of file edma_driver.h.
uint32_t minorByteTransferCount |
Number of bytes to be transferred in each service request of the channel.
Definition at line 378 of file edma_driver.h.
bool scatterGatherEnable |
Enable scatter gather feature.
Definition at line 380 of file edma_driver.h.
uint32_t scatterGatherNextDescAddr |
The address of the next descriptor to be used, when scatter/gather feature is enabled. Note: this value is not used when scatter/gather feature is disabled.
Definition at line 381 of file edma_driver.h.
uint32_t srcAddr |
Memory address pointing to the source data.
Definition at line 363 of file edma_driver.h.
int32_t srcLastAddrAdjust |
Last source address adjustment.
Definition at line 373 of file edma_driver.h.
edma_modulo_t srcModulo |
Source address modulo.
Definition at line 376 of file edma_driver.h.
int16_t srcOffset |
Sign-extended offset applied to the current source address to form the next-state value as each source read/write is completed.
Definition at line 367 of file edma_driver.h.
edma_transfer_size_t srcTransferSize |
Source data transfer size.
Definition at line 365 of file edma_driver.h.
