Memory Map
ROM Memory Map
The ROM memory map is shown in figure 1 and described below.
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-$0FFF (HD404354, HD40A4354), $0000–$17FF (HD404356, HD40A4356),
$0000–$1FFF (HD404358, HD40A4358), $0000–$3FFF (HD407A4359)): 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.
