PROGRAM ROM ( 3K X 8 bits )

PROGRAM ROM ( 3K X 8 bits )

3 K x 8 bits program ROM contains user's program and some fixed data .

The basic structure of program ROM can be divided into 4 parts.

1. Address 000h: Reset start address.

2. Address 002h - 00Ch: 4 kinds of interrupt service routine entry addresses .

3. Address 00Eh-086h : SCALL subroutine entry address, only available at 00Eh,016h,01Eh,026h, 02Eh,

036h, 03Eh, 046h, 04Eh, 056h, 05Eh, 066h, 06Eh, 076h ,07Eh, 086h .

4. Address 000h - 7FFh : LCALL subroutine entry address

5. Address 000h - BFFh : Except used as above function, the other region can be used as user's program region.
