TRAN_SPEED bit
2:0
6:3
7
These Renesas MultiMediaCards support a transfer rate between 0 and 20 Mbit/s. The parameter
TRAN_SPEED is 0x2A.
The MultiMediaCard command set is divided into subsets (command classes). The card command class
register CCC defines which command classes are supported by this card. A set CCC bit means that the
corresponding command class is supported. For command class definition refer to Table “Command
Classes”.
