n ROM Area
• Vector table area (address: FFFC00
– This area is used as the vector tables for vector call instructions, interrupt vectors, and reset vectors.
– This area is allocated at the top of the ROM area.
processing routine is set to the address of each vector table as data.
• Program area (address: to FFFBFF
– ROM is contained as the internal program area.
– The capacity of the internal ROM depends on the product.
n RAM area
• Data area (address: 000100
– Static RAM is contained as the internal data area.
– The capacity of the internal RAM depends on the product.
• General-purpose register area (address: 000180
– Auxiliary registers for operations or transfer of the 8-bit, 16-bit, or 32-bit data are allocated in this area.
– This area is allocated to part of the RAM area, and can also be used as ordinary RAM.
– When this area is used as general-purpose registers, they can be accessed quickly using a short
instruction through general-purpose register addressing.
• Expansion intelligent I/O service (EI
– This area holds the transfer mode, I/O address, transfer count, and buffer address.
– This area is allocated to part of the RAM area, and can also be used as ordinary RAM.
n I/O area
• Interrupt control register area (address: 0000B0
The interrupt control registers (ICR00 to ICR15) handle all resources with an interrupt function, and control
the interrupt level setting and EI
• Resource control register area (address: 000020
This area controls the internal resources and performs data I/O.
• I/O Port control register area (address: 000000
This area controls the I/O ports and performs data I/O.
