Note:
Figure 1 ROM Memory Map
Vector Address Area ($0000 to $000F):
Locations $0000 through $000F are reserved for JMPL
instructions to branch to the starting address of the initialization program and of the interrupt programs.
After reset or an interrupt routine, the program is executed from the vector address.
Zero-Page Subroutine Area ($0000 to $003F):
Locations $0000 through $003F are reserved for
subroutines. The program sequence branches to subroutines by the CAL instruction.
Pattern Area ($0000 to $0FFF):
Locations $0000 through $0FFF are reserved for ROM data. The P
instruction allows the MCU to reference ROM data as a pattern.
Program Area ($0000 to $07FF: HD404812, HD40L4812; $0000 to $0FFF: HD404814, HD40L4814;
$0000 to $17FF: HD404816, HD40L4816; $0000 to $1FFF: HD404818, HD40L4818, HD4074818,
HD407L4818):
Used for program coding.
