4.3 Addressing of Data Memory
Figure 4-3 shows addressing of the data memory.
An address of the data memory is specified by a bank, a row address, and a column address.
The row address and column address are directly specified by using a data memory manipulation instruction.
The bank is specified by the contents of the bank register.
For the details of the bank register, refer to 5. SYSTEM REGISTER (SYSREG).
