Card identification (CID) register
The CID register is 16 bytes long and contains a unique card identification number used
during the card identification procedure. It is a 128 bit wide register with the content as
defined in
by MultiMediaCard hosts.
Table 33.
Card specific data register (CSD)
All the configuration information required to access the device data is stored in the CSD
register. The MSB bytes of the register contain the manufacturer data and the two least
significant bytes contains the host controlled data (the device Copy, Write Protection and the
user ECC register).
The host can read the CSD register and alter the host controlled data bytes using the
SEND_CSD and PROGRAM_CSD commands.
In
Programmable (R/W) or erasable (R/W/E). The programmable part of the register (entries
marked by W or E) can be changed by command CMD27.
The Copy bit in the CSD can be used to mark the device as an original or a copy. Once set it
cannot be cleared. The device can be purchased with the copy bit set (copy) or cleared,
indicating the device is a master.
The One Time Programmable (OTP) characteristic of the Copy bit is implemented in the
MultiMediaCard controller firmware and not with a physical OTP cell.
