Description
Writes a header to the CARDSPI FIFO, writes the first write buffer, reads the response to the first read buffer, writes the second write buffer, and reads the response to the second read buffer. To use this, the ARM9 Access Control bit for SPICARD must be set in one of the currently running ARM11 processes.
If the header, footer, or any of the buffers have a size of 0, their respective operation will be skipped.
