Hello,
is it possible to let the chip select go low after spiXfer? I need this for a project in which I move bytes one after the other via the SPI. After 10 bytes, for example, I have to set the chip select to high again. The problem is that I cannot fill the FIFO continuously, sometimes there are a few microseconds in between, which is why the spi automatically sets the chipselect high again, this must not happen.

Hmm, I thought this api accepts a buffer up to 64K (IIRC) and keeps the FIFO full. Can you send me more information on what you are seeing with perhaps a short code snippet?
