When read data is received, this bit is set to 1 after FIFO has
been full. This bit is cleared to 0 when RD_CONTI is set to 1
or command sequence is ended.
0: The FIFO is empty
1: The FIFO is full
When write data is transmitted, this bit is set to 1 after FIFO
has been empty. This bit is cleared to 0 when DATAEN is
set to 1 or command sequence is ended.
0: The FIFO includes data

Description
Command Busy
Indicates command execution state. When the CMDOFF bit
in OPCR is set to 1, this bit is cleared to 0 because the
MMCIF command sequence is aborted.
0: Idle state waiting for a command, or data busy state
1: Command sequence execution in progress
START bit in CMDSTRT has not been set yet, so the new
command can be written.
being transmitted. If the new command is written, a
malfunction will result.
