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–$1FFF: HD404848; $0000–$2FFF: HD4048412; $0000–$3FFF: HD404849,
HD4074849):
Used for program coding.
