OSPI_Transaction Struct Reference

Detailed Description

Data structure used with OSPI_Transfers - OSPI_readDirect, OSPI_writeDirect, OSPI_readIndirect, OSPI_writeIndirect.

It indicates how many OSPI_FrameFormat frames are sent and received from and to the buffer buf.

Data Fields
uint32_t	count
void *	buf
uint32_t	addrOffset
uint32_t	status
uint32_t	transferTimeout
uint32_t	dmaCopyLowerLimit

Field Documentation

count

uint32_t OSPI_Transaction::count

[IN] Number of frames for this transaction

buf

void* OSPI_Transaction::buf

[IN] void * to a buffer to receive/send data

addrOffset

uint32_t OSPI_Transaction::addrOffset

[IN] Address offset to write to an OSPI flash device.

status

uint32_t OSPI_Transaction::status

[OUT] OSPI_TransferStatus code set by OSPI_Transfers

transferTimeout

uint32_t OSPI_Transaction::transferTimeout

[IN] Timeout of the specific transfer

dmaCopyLowerLimit

uint32_t OSPI_Transaction::dmaCopyLowerLimit

[IN] Minimum bytes of data for which DMA copy takes lesser time than pointer copy
