software example. A dot line square area shows one memory and each dot line square shows
to BANK register of LOCAL3 area upper 5-bit address of access point.
upper address bit of BANK register is meaningless. 4-bits of upper 5-bits address means 16
BANKs. After setting BANK5, accessing 800000H to BFFFFFH address: logical LOCAL3
