8 / 103 page HD404054 Series/HD404094 Series 6 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. 0 15 16 63 64 2047 0 $000F $07FF $003F $0040 Vector address Zero-page subroutine (64 words) Program & Pattern 2048 words (HD404052, HD40A4052, HD404092) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 $0000 $0000 $0001 $0002 $0003 $0004 $0005 $0006 $0007 $0008 $0009 $000A $000B $000C $000D $000E $000F 0 1 JMPL instruction (Jump to RESET, STOPC routine) JMPL instruction (Jump to INT routine) JMPL instruction (Jump to timer A routine) JMPL instruction (Jump to timer D, routine) JMPL instruction (Jump to INT routine) JMPL instruction (Jump to serial 1 routine) JMPL instruction (Jump to timer C, routine) Not used $0010 4096 words (HD404054, HD40A4054, HD4074054,HD404094, HD4074094) 4095 $0FFF 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. |
