ISTA : Insertion Status. It reflects the Memory Stick card presence. This is the inverse of INS pin.
RDY : Ready. RDY goes to 1 when the protocol ends. This bit bit is cleared to 0 by write to the command register.
EMP : FIFO Empty. This bit is set to 1 by writing system register bit FCLR=1.
FUL : FIFO Full. This bit is cleared to 0 by writing system register bit FCLR=1.
CED : MS Command End.
ERR : Memory Stick Error.
0 : No card.
1 : Card is inserted.
0 : Command receive disabled due to communication with the Memory Stick.
1 : Command received or protocol ended.
0 : FIFO contains data.
1 : FIFO is empty.
0 : FIFO has empty space.
1 : FIFO is full.
