Figure 1 ROM Memory Map

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

of the reset and interrupt routines. After MCU reset or an interrupt, program execution continues from the

vector address.

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–$1FFF: HD404828R; $0000–$2FFF: HD4048212R; $0000–$3FFF;

HD404829R, HD4074829): Used for program coding.
