• Special Function Register (SFR) Area

The special function register (SFR) area contains the registers

relating to functions such as I/O ports and timers.

• RAM

RAM is used for data storage as well as a stack area.

• ROM

ROM is used for storing user programs as well as the interrupt

vector area.

• Interrupt Vector Area

The interrupt vector area is for storing jump destination ad-

dresses used at reset or when an interrupt is generated.

• Zero Page

Zero page addressing mode is useful because it enables access

to this area with fewer instruction cycles.

• Special Page

Special page addressing mode is useful because it enables ac-

cess to this area with fewer instruction cycles.
