=Description=
Writes data to the [[SPICARD_Registers|CARDSPI FIFO]], reads the response, writes more data, and reads the next response. To use this, the [[NCCH/Extended_Header|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.
