PROGRAM ROM ( 32K X 8 bits )

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

The basic structure of the program ROM may be categorized into 5 partitions.

1. Address 0000h: Reset start address.

2. Address 0002h - 000Ch : 5 kinds of interrupt service routine entry addresses .

3. Address 000Eh-0086h : SCALL subroutine entry address, only available at 000Eh,0016h,001Eh,0026h,

002Eh, 0036h, 003Eh, 0046h, 004Eh, 0056h, 005Eh, 0066h, 006Eh, 0076h, 007Eh,

0086h .

4. Address 0000h - 07FFh : LCALL subroutine entry address.

5. Address0000h-1FFFh:Exceptusedasabovefunction,theotherregioncanbeusedasuser'sprogramanddataregion.
