Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

These bits cause the cards to enter pre-idle state, which requires them to be re-initialized.
■ CARD_RESET[0] should be set to 1’b0 to reset card number 0
■ CARD_RESET[15] should be set to 1'b0 to reset card number 15.
The number of bits implemented is restricted to NUM_CARDS.
