SPI interrupt control register

Structs

DMA_SEG_MAGIC_VALUE_R

Field DMA_SEG_MAGIC_VALUE reader - The magic value of BM table in master DMA seg-trans.

DMA_SEG_MAGIC_VALUE_W

Field DMA_SEG_MAGIC_VALUE writer - The magic value of BM table in master DMA seg-trans.

R

Register SLV_RD_BYTE reader

SLV_DATA_BYTELEN_R

Field SLV_DATA_BYTELEN reader - The full-duplex or half-duplex data byte length of the last SPI transfer in slave mode. In half-duplex mode, this value is controlled by bits [23:20] .

SLV_DATA_BYTELEN_W

Field SLV_DATA_BYTELEN writer - The full-duplex or half-duplex data byte length of the last SPI transfer in slave mode. In half-duplex mode, this value is controlled by bits [23:20] .

SLV_RDBUF_BYTELEN_EN_R

Field SLV_RDBUF_BYTELEN_EN reader - 1: SPI_SLV_DATA_BYTELEN stores data byte length of master-read-slave data length in CPU controlled mode(Rd_BUF). 0: others

SLV_RDBUF_BYTELEN_EN_W

Field SLV_RDBUF_BYTELEN_EN writer - 1: SPI_SLV_DATA_BYTELEN stores data byte length of master-read-slave data length in CPU controlled mode(Rd_BUF). 0: others

SLV_RDDMA_BYTELEN_EN_R

Field SLV_RDDMA_BYTELEN_EN reader - 1: SPI_SLV_DATA_BYTELEN stores data byte length of master-read-slave data length in DMA controlled mode(Rd_DMA). 0: others

SLV_RDDMA_BYTELEN_EN_W

Field SLV_RDDMA_BYTELEN_EN writer - 1: SPI_SLV_DATA_BYTELEN stores data byte length of master-read-slave data length in DMA controlled mode(Rd_DMA). 0: others

SLV_RD_BYTE_SPEC

SPI interrupt control register

SLV_RD_DMA_DONE_R

Field SLV_RD_DMA_DONE reader - The interrupt raw bit for the completion of Rd-DMA operation in the slave mode. Can not be changed by CONF_buf.

SLV_RD_DMA_DONE_W

Field SLV_RD_DMA_DONE writer - The interrupt raw bit for the completion of Rd-DMA operation in the slave mode. Can not be changed by CONF_buf.

SLV_WRBUF_BYTELEN_EN_R

Field SLV_WRBUF_BYTELEN_EN reader - 1: SPI_SLV_DATA_BYTELEN stores data byte length of master-write-to-slave data length in CPU controlled mode(Wr_BUF). 0: others

SLV_WRBUF_BYTELEN_EN_W

Field SLV_WRBUF_BYTELEN_EN writer - 1: SPI_SLV_DATA_BYTELEN stores data byte length of master-write-to-slave data length in CPU controlled mode(Wr_BUF). 0: others

SLV_WRDMA_BYTELEN_EN_R

Field SLV_WRDMA_BYTELEN_EN reader - 1: SPI_SLV_DATA_BYTELEN stores data byte length of master-write-to-slave data length in DMA controlled mode(Wr_DMA). 0: others

SLV_WRDMA_BYTELEN_EN_W

Field SLV_WRDMA_BYTELEN_EN writer - 1: SPI_SLV_DATA_BYTELEN stores data byte length of master-write-to-slave data length in DMA controlled mode(Wr_DMA). 0: others

USR_CONF_R

Field USR_CONF reader - 1: Enable the DMA CONF phase of current seg-trans operation, which means seg-trans will start. 0: This is not seg-trans mode.

USR_CONF_W

Field USR_CONF writer - 1: Enable the DMA CONF phase of current seg-trans operation, which means seg-trans will start. 0: This is not seg-trans mode.

W

Register SLV_RD_BYTE writer
