5.1 Mutimedia card
5.2 Secure digital memory card
There is one additional signal needed in the interface, a power control line MCIPWR, but it
can be sourced from any GPIO signal.
The MCI may be used as a multimedia card bus host (see
card”) or a secure digital memory card bus host (see
memory
digital memory card may be connected.
Figure 21–104
Multimedia cards are grouped into three types according to their function:
The multimedia card system transfers commands and data using three signal lines:

Read Only Memory (ROM) cards, containing pre-programmed data
Read/Write (R/W) cards, used for mass storage
Input/Output (I/O) cards, used for communication
CLK: One bit is transferred on both command and data lines with each clock cycle.
The clock frequency varies between 0 MHz and 20 MHz (for a multimedia card) or
0 MHz and 25 MHz (for a secure digital memory card).
CMD: Bidirectional command channel that initializes a card and transfers commands.
CMD has two operational modes:
– Open-drain for initialization
– Push-pull for command transfer
DAT: Bidirectional data channel, operating in push-pull mode
