26.3.14 Transfer Clock Control Register (CLKON)
CLKON controls the transfer clock frequency and clock ON/OFF.
Bits CSEL2 to CSEL0 must be set to 100 for the peripheral clock to be 20-MHz in order to
achieve a 20-Mbps transfer clock in the MMCIF. At this time, bits CSEL2 to CSEL0 should be set
to 000 for the 200-kbps transfer clock in Card Identification Mode in MMC mode.
In a command sequence, do not perform clock ON/OFF or frequency modification.
