Cannot change the value of SPI1->RSER

#define SPI_RSER_TFFF_DIRS_MASK                  0x1000000u



I try to activate the interrupt bit for TFFF RE in the SPI1 register RSER

When I write to this register it has no affect.  The register is always 0 (Checked with ULINK 2)

If I do the same to SPI0 it works.


Is there an issue for SPI1 that the interrupt do not work?


Finally I would like to use the SPI1 transmit by a DMA process.

Has anyone experience with DMA on SPI1 in transmit direction?
