6.3 Argument Register (MCIArgument - 0xE008 C008)
6.4 Command Register (MCICommand - 0xE008 C00C)
Table 492: Clock Control register (MCIClock - address 0xE008 C004) bit description
While the MCI is in identification mode, the MCICLK frequency must be less than
400 kHz. The clock frequency can be changed to the maximum card bus frequency when
relative card addresses are assigned to all cards.
Note: After a data write, data cannot be written to this register for three MCLK clock
periods plus two PCLK clock periods.
The MCIArgument register contains a 32 bit command argument, which is sent to a card
as part of a command message.
MCIArgument register.
Table 493: Argument register (MCIArgument - address 0xE008 C008) bit description
If a command contains an argument, it must be loaded into the argument register before
writing a command to the command register.
The MCICommand register contains the command index and command type bits:

The command index is sent to a card as part of a command message.
The command type bits control the Command Path State Machine (CPSM). Writing 1
to the enable bit starts the command send operation, while clearing the bit disables
the CPSM.
