Table 11-13 describes the fields in the DSPI DMA / interrupt request and enable register.
Table 11-13. DSPIx_RSER field descriptions
Field Description
0
TCF_RE
Transmission complete request enable. Enables TCF flag in the DSPIx_SR to generate an interrupt
request.
0 TCF interrupt requests are disabled
1 TCF interrupt requests are enabled
1–2 Reserved.
3
EOQF_RE
DSPI finished request enable. Enables the EOQF flag in the DSPIx_SR to generate an interrupt
request.
0 EOQF interrupt requests are disabled
1 EOQF interrupt requests are enabled
4
TFUF_RE
Transmit FIFO underflow request enable. The TFUF_RE bit enables the TFUF flag in the DSPIx_SR
to generate an interrupt request.
0 TFUF interrupt requests are disabled
1 TFUF interrupt requests are enabled
5 Reserved.
6
TFFF_RE
Transmit FIFO fill request enable. Enables the TFFF flag in the DSPIx_SR to generate a request. The
TFFF_DIRS bit selects between generating an interrupt request or a DMA requests.
0 TFFF interrupt requests or DMA requests are disabled
1 TFFF interrupt requests or DMA requests are enabled
7
TFFF_DIRS
Transmit FIFO fill DMA or interrupt request select. Selects between generating a DMA request or an
interrupt request. When the TFFF flag bit in the DSPIx_SR is set, and the TFFF_RE bit in the
DSPIx_RSER is set, this bit selects between generating an interrupt request or a DMA request.
0 Interrupt request is selected
1 DMA request is selected
8–11 Reserved.
12
RFOF_RE
Receive FIFO overflow request enable. Enables the RFOF flag in the DSPIx_SR to generate an
interrupt request.
0 RFOF interrupt requests are disabled
1 RFOF interrupt requests are enabled
13 Reserved.
14
RFDF_RE
Receive FIFO drain request enable. Enables the RFDF flag in the DSPIx_SR to generate a request.
The RFDF_DIRS bit selects between generating an interrupt request or a DMA request.
0 RFDF interrupt requests or DMA requests are disabled
1 RFDF interrupt requests or DMA requests are enabled
