MMC Clock Enable Bit
Set to enable the MCLK clocks and activate the MMC controller.
Clear to disable the MMC clocks and freeze the MMC controller.
Data Controller Reset Bit
Set and clear to reset the data line controller in case of transfer abort.
Command Controller Reset Bit
Set and clear to reset the command line controller in case of transfer abort.
Reserved
The values read from these Bits are always 0. Do not set these Bits.
Used to delay the data transmission after a response from 3 MMC clock periods
(all Bits cleared) to 9 MMC clock periods (all Bits set) by step of 2 MMC clock
periods.
MMC Flow Control Bit
Set to enable the flow control during data transfers.
Clear to disable the flow control during data transfers.
Reserved
The values read from these Bits are always 0. Do not set these Bits.
Card Busy Flag
Set by hardware when the card sends a busy state on the data line.
Cleared by hardware when the card no more sends a busy state on the data line.
