Table 11-13 describes the fields in the DSPI DMA / interrupt request and enable register.
Table 11-13. DSPIx_RSER Field Descriptions
Field
0
TCF_RE
Description
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
DSPI finished request enable. Enables the EOQF flag in the DSPIx_SR to generate an interrupt
EOQF_RE request.
0 EOQF interrupt requests are disabled
1 EOQF interrupt requests are enabled
4
Transmit FIFO underflow request enable. The TFUF_RE bit enables the TFUF flag in the DSPIx_SR
TFUF_RE to generate an interrupt request.
5
6
TFFF_RE
0 TFUF interrupt requests are disabled
1 TFUF interrupt requests are enabled
Reserved.
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
Transmit FIFO fill DMA or interrupt request select. Selects between generating a DMA request or an
TFFF_DIRS 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
Receive FIFO overflow request enable. Enables the RFOF flag in the DSPIx_SR to generate an
RFOF_RE interrupt requests.
0 RFOF interrupt requests are disabled
1 RFOF interrupt requests are enabled
13
Reserved.
14
Receive FIFO drain request enable. Enables the RFDF flag in the DSPIx_SR to generate a request.
RFDF_RE 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
