OVERVIEW

The S3C9484/C9488/F9488 microcontroller has two kinds of address space:

— Internal program memory (ROM)

— Internal register file

A 13-bit address bus supports program memory operations. A separate 8-bit register bus carries addresses and

data between the CPU and the internal register file.

The S3F9488 have 8-Kbytes of on-chip program memory, which is configured as the Internal ROM mode, all of the 8-

Kbyte internal program memory is used.

The S3C9484/C9488/F9488 microcontroller has 208 general-purpose registers in its internal register file. 47 bytes in

the register file are mapped for system and peripheral control functions. And 19 bytes in the page1 is mapped for

LCD display data area.
