24.3.1
The CMDR registers are six 8-bit registers. A command is written to CMDR as shown in table
24.4, and the command is transmitted when the START bit in CMDSTRT is set to 1. Each
command is transmitted in order form the MSB (bit 7) in CMDR0 to the LSB (bit 0) in CMDR5.

Operation
Write command arguments.
Setting of CRC is unnecessary (automatic calculation).
End bit is fixed to 1 and its setting is unnecessary
(automatic setting).
The read value is 0.
Description
Command arguments
See specifications for the MMC card.
Description
These bits are always read as 0. The write value should
always be 0.
This bit is always read as 0. The write value should
always be 0.
