This bit is set to “1” when the RRDY/−BSY bit changes state. The host may also write this bit.
When read, this bit indicates +READY pin states. When written, this bit is used for CRDY/−BSY
bit masking.
These fields are used for the configuration of the plural cards. When host configures the plural
cards, written the card’s copy number in this field. In this way, host can perform the card’s
master/slave organization.
