Note:
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 an MCU reset or interrupt execution, the program starts 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–$07FF (HD404612), $0000–$0FFF (HD404614), $0000–$17FF (HD404616),
$0000–$1FFF (HD404618, HD4074618)):
Used for program coding.
