Figure 20-7. DSPI DMA/Interrupt Request Select and Enable Register (DSPIx_RSER)
Table 20-7. DSPIx_RSER Field Descriptions
Bits Name 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 will be generated
1 DMA request will be generated
8–11 — Reserved.
