MEMORY
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.
