2.5 RAM
The 512-byte internal RAM is positioned at $0040–$023F in the memory map. The lower 192 bytes are
positioned in the page zero which are accessible by the direct addressing mode. The upper 64 bytes of
this area (page zero) are used for the CPU stack. Care should be taken if the stack area is used for data
storage.
The remaining 320 bytes of RAM, $0100–$023F, are accessed by extended addressing mode.
The RAM is implemented with static cells and retains its contents during the stop and wait modes.
2.6 Self-Check ROM
Self-check ROM is 496 bytes of mask ROM positioned at $FE00–$FFEF. This ROM contains self-check
programs and reset/interrupt vectors in the self-check mode.
2.7 Mask ROM
The 16,384-byte user ROM is positioned at $1000–$4FFF, and an additional 16 bytes of ROM are located
at $FFF0–$FFFF for user vectors.
