Ready/-Busy Pin Status (Read Only)
This bit reflects the Ready/-Busy pin status of Smart Media card.
Card Detect Pin Status of SM1 (Read Only)
This bit is the card detect pin status of SM1, and it is using for card detection.
When there is a card inserted in or removed from SM1, software should check
this bit to confirm if there is really a card insertion or remove.
Card Detect Pin Status of SM0 (Read Only)
This bit is the card detect pin status of SM0, and it is using for card detection.
When there is a card inserted in or removed from SM0, software should check
this bit to confirm if there is really a card insertion or remove.
Ready/-Busy Rising Edge Detect Interrupt Flag (Read Only)
 0 = R/-B rising edge is not detected.
 1 = R/-B rising edge is detected.
NOTE: This bit is read only, but can be cleared by writing ‘1’ to it.
SM Card 1 Detection Interrupt Flag (Read Only)
This bit indicates that SM card 1 is inserted or removed. Only if
SMIER[CD1_IE] is set to 1, this bit is active.
 0 = No card is inserted or removed.
 1 = There is a card inserted in or removed from SM1.
NOTE: This bit is read only, but can be cleared by writing ‘1’ to it.
SM Card 0 Detection Interrupt Flag (Read Only)
This bit indicates that SM card 0 is inserted or removed. Only if
SMIER[CD0_IE] is set to 1, this bit is active.
 0 = No card is inserted or removed.
 1 = There is a card inserted in or removed from SM0.
NOTE: This bit is read only, but can be cleared by writing ‘1’ to it.
