Description
Reserved
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 to 0 after the MMCIF received
the CMDSTART command. When 0 is written to this bit,
operation is not affected.
Description
Command Off
Aborts all command operations (MMCIF command
sequence) when 1 is written after a command is
transmitted. This bit is cleared to 0 automatically after
the MMCIF received the CMDOFF command.
Write enabled period: From command transmission
completion to command sequence end
Write of 0: Operation is not affected.
Write of 1: Command sequence is forcibly aborted.
Note: Do not write to this bit out of the write enable
