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 (HD404324, HD404324U: $0000-$0FFF; HD404326, HD404326U: $0000-$17FF;
HD404328, HD404328U: $0000–$1FFF; HD4074329, HD4074329U: $0000–$3FFF):
Used for program
coding.
