RM0400
Field
DSI Frame Transfer Complete Flag.
Similar to TCF but only asserted on DSI frame transmission completion in CSI Mode.
5
This includes ITSB and 'TSB in CSI' modes, but not SPI or DSI Modes.
DSITCF
0 DSI frame transfer is not complete.
1 DSI frame transfer is complete.
Transmit FIFO Fill Flag.
Provides a method for the DSPI to request more entries to be added to the TX FIFO. The TFFF
bit is set while the TX FIFO is not full.
6
The TFFF bit can be cleared by writing '1' to it or by acknowledgement from the DMA controller to
TFFF
the TX FIFO full request.
0 Tx FIFO is full.
1 Tx FIFO is not full.
Busy Flag.
This bit is valid only when DSPI_MCR[XSPI] is enabled.
Indicates that the current Command Frame is being used for transmitting multiple data frames.
This bit is not set for the last Data Frame of a Cyclic command Transfer or when
7 DSPI_CTARE[DTCP] = 1.
BSYF See Section 46.5.2.5: Command First In First Out (CMD FIFO) buffering
This bit is valid only when DSPI_MCR[XSPI] is enabled.
0No Cyclic Command Transfer in Progress.
1 Cyclic Command Transfer is in progress. Current Data Frame is not the last data frame for
current cyclic command transfer.
Command Transfer Complete Flag.
Indicates that the last Data frame for the current Cyclic Command has been transmitted. Hence
this bit is set only for the last Data Frame of a Cyclic Command Transfer or when
8
DSPI_CTARE[DTCP] = 1.
CMDTCF
CMDTCF remains set until it is cleared by writing a '1' to it.
0 Data Transfer by current Command not complete.
1 Data Transfer by current Command complete.
DSI Parity Error Flag.
9
Indicates that a DSI frame with parity error has been received.
DPEF
0 No parity error.
1 Parity error has occurred.
SPI Parity Error Flag.
10
Indicates that a SPI frame with parity error has been received.
SPEF
0 No parity error.
1 Parity error has occurred.
DSI Data Received with Active Bits.
Indicates that a DSI frame has been received with bits selected by DIMR with active polarity,
11
defined by the DPIR.
DDIF
0 No DSI data with active bits was received.
1 DSI data with active bits was received.
