ADDRESS SPACES

2.1 OVERVIEW OF ADDRESS SPACES
The S3F84B8 microcontroller consists of two kinds of address spaces, namely:

Internal program memory (ROM)

Internal register file
A 16-bit address bus supports program memory operations. On the other hand, a separate 8-bit register bus
carries addresses and data between the CPU and internal register file.
The S3F84B8 microcontroller contains 8Kbytes of on-chip program memory configured as Internal ROM. It also
contains 272 general-purpose registers in the internal register file, where 59 bytes are mapped for system and
peripheral control functions.
