19.3.1
Mode Register (MODER)
MODER specifies the MCIF operating mode. The two operating modes have different
input/output pin functions, usable command types, and command sequence. In each mode, the
following sequence should be repeated when the MCIF uses the MMC: Send a command, wait for
the end of the command sequence and the end of the data busy state, and send the next command.
The series of operations from command sending, command response reception, data
transmission/reception, and data response reception is called the command sequence. The
command sequence starts from sending a command by setting the START bit in CMDSTRT to 1,
and ends when all necessary data transmission/reception and response reception has been
completed. The MMC supports the data busy state in which the next command is not accepted to
write/erase data to/from the flash memory in the MMC during command sequence execution and
after command sequence execution has ended. The data busy state is indicated by a 0 output from
the MMC side to the MCDAT pin in MMC mode, and to the MCRxD pin in SPI mode.
