version 4.0, and higher, of the specification, the value shall be 20 MHz (0x2A):
Table 38.
CCC
The MultiMediaCard command set is divided into subsets (command classes). The card
command class register CCC defines which command classes are supported by this device.
A value of ‘1’ in a CCC bit means that the corresponding command class is supported. For
command class definition refer to
Table 39.
READ_BL_LEN
The purpose of this field is to indicate the maximum data block length that is supported by
the device when performing read operations.
The data block length is computed as 2
from one to 16 Kbytes.
After power-up or software reset, the device defaults to operate in 512-byte block length.
Table 40.
1. This bit is only available for the NAND16GAH0D. It must be set to ‘0’ for the NAND08GAH0A.
