Hallo everyone,
I'm trying to implement SPI TX with DMA using RH850/F1KM-S4 and try to implement following flow
chip select pin Low --> write first data to CSIG2TX0H --> INTDMA0 triggerd, set flag A --> IF A & !(CSIG2STR0&(1<<7) --> chip select pin high.
On the oscilloscope i can confirm that chip select pin was toggled high -> low -> high. But only the first data was transmitted (i.e. DMA transfer is not happening).
How can INTDMA0 is still triggered?
I tried to post code snippets here. but it seems it didn't work.
