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 (HD404314), $0000–$17FF (HD404316), $0000–$1FFF (HD404318,
HD4074318)):
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.
