4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
Preliminary
10.15.2002 (V1.3)
FUNCTION DESCRIPTIONS
PROGRAM ROM ( 16K X 8 bits )
16 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 : 6 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. Address 0000h - 1FFFh : Except used as above function, the other region can be used as user's program and
data region.
