Figure 9.9 Operation in the Indirect Address mode in the Dual Address Mode
Note:
When the value in SAR_3 is an address, the memory data is read and the value is
stored in the temporary buffer. The value to be read must be 32 bits since it is used
for the address.
When the value in the temporary buffer is an address, the data is read from the
transfer source module to the data buffer.
When the value in SAR_3 is an address, the value in the data buffer is written to the
transfer source module.
The above description uses the memory, transfer source module, or transfer
destination module; in practice, any module can be connected in the addressing
space.
