IDE and Flash Media Interface
13.5.5
Before any data exchange is possible with the Memory Stick, the FLASHMEDIACONFIG register must
be written to set up the clock and the card type. After this, the card is accessed by issuing one of three
possible command sequences. Each new command sent to the card, must toggle the BS line going out. The
“handshake” phase of the Memory Stick can be implemented as a 16-bit read. There is no specific
handshake command.

Flash Media Interface Operation in Memory Stick Mode
The Flash Media interface can handle two Memory Stick cards. One is
attached to the primary interface, the other to the secondary interface. There
is one potential issue. If there is a buffer full or a buffer empty on one
interface, the system will freeze the outgoing SCLK signal, which causes
the second interface to go into a wait-state as well.
