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 (HD404364, HD40A4364), $0000–$1FFF (HD404368, HD40A4368),
$0000–$2FFF (HD4043612, HD40A43612), $0000–$3FFF (HD404369, HD40A4369, HD407A4369)):
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.

RAM Memory Map
The MCU contains 512-digit
×
4 bit RAM areas. These RAM areas consist of a memory register area, a
data area, and a stack area. In addition, an interrupt control bits area, special function register area, and
register flag area are mapped onto the same RAM memory space labeled as a RAM-mapped register area.
The RAM memory map is shown in figure 2 and described below.
