MEMORY
• Special Function Register (SFR) Area
The Special Function Register area in the zero page contains
control registers such as I/O ports and timers.
• RAM
RAM is used for data storage and for stack area of subroutine
calls and interrupts.
• ROM
The first 128 bytes and the last 2 bytes of ROM are reserved for
device testing and the rest is user area for storing programs.
In the QzROM version, 1 byte of address FFDB
reserved area.
• Interrupt Vector Area
The interrupt vector area contains reset and interrupt vectors.
• Zero Page
Access to this area with only 2 bytes is possible in the zero page
addressing mode.
• Special Page
Access to this area with only 2 bytes is possible in the special
page addressing mode.
