Note:
Data is read from memory using the SAR3 value as the data address, and the read
data is stored in the temporary buffer. The read data must be a 32-bit value because it
is used as an address.
Two bus cycles are required if a 16-bit data bus is used to connect to an external
device.
Data is read from the source module using the temporary buffer value as the address,
and the read data is transferred to the data buffer.
The data buffer value is written to the destination module using the DAR3 value as the
destination address.
(When the External Memory Space is Set to 16-bit Width)
The above description uses the memory, transfer source module, or transfer
destination module; in practice, any module can be connected in the addressing
space.
