MPC5554: Non-trivial DSPI-DMA transfer

Question asked by Vyacheslav Krutov on Apr 22, 2015

Is it possible to configure DSPI-DMA mode such way that allows to automaticaly transfer several KB data array from a memory location  outside over SPI bus ?

So, when SPI TX FIFO would be full, DMA will stall and wait till an empty entry in FIFO after word shifting out would be available to continue DMA operation.

 

Thanks.
