Memory Map

ROM Memory Map

Vector Address Area ($0000–$000F): Reserved for JMPL instructions that branch to the start addresses

of the reset and interrupt routines.

Zero-Page Subroutine Area ($0000–$003F): Reserved for subroutines. The program branches to a

subroutine in this area in response to the CAL instruction.

Pattern Area ($0000–$0FFF): Contains ROM data that can be referenced with the P instruction.

Program Area ($0000-$0FFF (HD404334), $0000-$17FF (HD404336), $0000–$1FFF (HD404338),

$0000–$2FFF (HD4043312), $0000–$3FFF (HD404339, HD4074339)): The entire ROM area can be

used for program coding.

Note:

Since the ROM address areas between $0000–$0FFF overlap, the user can determine how these

areas are to be used.
