26.3.7
CMDSTRT is an 8-bit readable/writable register that triggers the start of command transmission,
representing the start of a command sequence. The following operations should have been
completed before the command sequence starts.
• Analysis of prior command response, clearing the command response register write if
• Analysis/transfer of receive data of prior command if necessary
• Preparation of transmit data of the next command if necessary
• Setting of CMDTYR, RSPTYR, and TBCR
• Setting of CMDR0 to CMDR4
Command sequences are controlled by the sequencers in both the MMCIF side and the MMC card
side. Normally, these operate synchronously. However, if an error occurs or a command is
aborted, these may become temporarily unsynchronized. Be careful when setting the CMDOFF bit
in OPCR, issuing the CMD12 command, or processing an error in MMC mode. A new command
sequence should be started only after the end of the command sequence on both the MMCIF and
card sides is confirmed.

The CMDR0 to CMDR4, CMDTYR, RSPTYR, and TBCR registers should not be changed
until command transmission has ended (the CWRE flag in CSTR has been set to 1).

These bits are always read as 0. The write value should
always be 0.
Starts command transmission when 1 is written. This bit is
automatically cleared. When 0 is written to this bit, its
previous value is retained.
