1. See
2. ‘r’ and ‘w’ stand for read and write.
3. If the device was previously selected and was in Transfer state, its connection with the host is released and it moves back
4. Issuing the CMD7 command along with the reserved RCA 0x0000 returns to Standby state.
5. CMD7 commands issued along with the device RCA while the device is in Transfer state are ignored and may be treated as
6. After the device is assigned an RCA it will not respond to identification commands, CMD1, CMD2, or CMD3.
7. The SET_DSR (CMD4) broadcast command configures the device driver stages. It programs its DSR register according to
8. The busy (Dat0=Low) is always active when the device is in Programming state. A host should not send CMD24/CMD25

while the device is in the Programming state and busy is active. However to ensure compatibility with previous
MultiMediaCard specification, the device treats CMD24 and CMD25 as legal or illegal commands when in Programming
