9 / 65 page HD404019R Series 7 Memory Map ROM Memory Map The MCU contains a 16,384-word × 10-bit ROM (mask ROM or PROM). It is described in the following paragraphs and by the ROM memory map in figure 1. 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 is processed, the program is executed from the vector address. Zero-Page Subroutine Area ($0000 to $003F): Locations $0000 through $003F are reserved for subroutines. The CAL instruction branches to subroutines. Pattern Area ($0000 to $0FFF): Locations $0000 through $0FFF are reserved for ROM data. The P instruction can refer to the ROM data as a pattern. Program Area ($0000 to $3FFF): Locations from $0000 to $3FFF can be used for program code. 0 15 16 63 64 4095 4096 16383 $0000 $0FFF $1000 $3FFF $0000 $0001 $0002 $0003 $0004 $0005 $0006 $0007 $0008 $0009 $000A $000B $000C $000D $000E $000F JMPL instruction (jump to reset routine) JMPL instruction (jump to INT0 routine) JMPL instruction (jump to INT1 routine) JMPL instruction (jump to timer A routine) JMPL instruction (jump to timer B routine) JMPL instruction (jump to serial routine) Vector address Zero-page subroutine (64 words) Pattern (4096 words) Program (16,384 words) $000F $0010 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 $003F $0040 Figure 1 ROM Memory Map |
