Register
(MODER)
MODER is an 8-bit readable/writable register that specifies the MMCIF operating mode. The
following sequence should be repeated when the MMCIF uses the multimedia card: Send a
command, wait for the end of the command sequence and the end of the data busy state, and send
a next command.
The series of operations from command sending, command response reception, data
transmission/reception, and data response reception is called as 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 have been
completed. The multimedia card supports the data busy state such that only the specific command
is accepted to write/erase data to/from the flash memory in the card during command sequence
execution and after command sequence execution has ended. The data busy state is indicated by a
low level output from the card side to the MCDAT pin.
