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–$07FF (HD404052, HD40A4052, HD404092), $0000–$0FFF (HD404054,
HD40A4054, HD4074054, HD404094, HD4074094)):
Used for program coding.

Figure 1 ROM Memory Map
RAM Memory Map
The MCU contains a 512-digit
×
4-bit RAM area consisting of a memory register area, a data area, and a
stack area. In addition, an interrupt control bits area, special register area, and register flag area are mapped
onto the same RAM memory space as a RAM-mapped register area outside the above areas. The RAM
memory map is shown in figure 2 and described as follows.
