CD : Card Detection.
TOE : Time Out Error.
CRC : CRC error.
MSINT : Memory Stick interruption.
DRQ : Data request, FIFO is full (reception) or empty (transmission).
PEND : Protocol End.
0 : No card detected. This bit is cleared when the correponding bit in ISCR is set to 1.
1 : This bit is set to 1 when a Memory Stick card is inserted or removed.
0 : This bit is cleared to 0 when the corresponding bit in ISCR it set to 1.
1 : This bit is set to 1 when protol ended with time out error.
0 : No CRC error. This bit is cleared when the corresponding bit in ISCR is set to 1.
1 : This bit is set when protocol ends with CRC error.
0 : This bit is cleared to 0 when the corresponding bit in ISCR is set to 1.
1 : This bit is set to 1 when an interrupt request INT is received from Memory Stick.
0 : This bit is cleared to 0 when data access is no more required.
1 : This bit is set to 1 when data access is required (read or write).
0 : This bit is cleared to 0 when the corresponding bit in ISCR is set to 1.
1 : This bit is set to 1 when protol ended witout error.
