Control Registers
LCDC display data), in each of 3 local areas (Local-X, Y and Z), providing easy data access.
There are 12 MMU registers, covering 4 functions (program, data read, data write and

outputs this to the physical address according to the bank number. The physical
address bus is output to the external address bus pin, thereby enabling access to
external memory.
(Example)
Note 1: Since the common area cannot be used as local area, do not set a bank number
Note 2: Changing program BANK number (LOCALPX, Y or Z) is disabled in the LOCAL
Note 3: After data bank number register (LOCALRn, LOCALWn or LOCALLn; where “n”
Note 4: When LOCAL-Z area is used, chip select signal
If COMMON-Z area is not used as data write memory, this setting is not required.
If COMMON-Z area is not used as LCD display memory, this setting is not required.
First, set the enable register and bank number for each LOCAL register.
The relevant pin and memory settings should then be set to the ports and memory
When the CPU or LCDC outputs a local area logical address, the MMU converts and
to LOCAL register which overlaps with the common area.

common area. (But bank setting of read data, write data and data for LCD display
can be changed in the local area.)

following instruction because several clocks are required for effective MMU

accesses SFR or another memory, as in the following example.
