4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
Preliminary
User's program and fixed data are stored in the program ROM. User's program is executed using the PC value to fetch an
instructioncode.
The 32Kx8 bits program ROM can be divided into 8 banks. There are 4Kx8 bits per bank.
The program ROM bank is selected by P3(2..0). The program counter is a 13-bit binary counter. The PC
and P3 are initialized to "0" during reset.
When P3(2..0)=000B, the bank0 and bank1 of program ROM will be selected. P3(2..0)=001B, the bank0 and
bank2 will be selected, and so on.
