Functional Description
Chapter 3 provides an overview of the SAA-XC886 functional description.
3.1
Processor Architecture
The SAA-XC886 is based on a high-performance 8-bit Central Processing Unit (CPU)
that is compatible with the standard 8051 processor. While the standard 8051 processor
is designed around a 12-clock machine cycle, the SAA-XC886 CPU uses a 2-clock
machine cycle. This allows fast access to ROM or RAM memories without wait state.
Access to the Flash memory, however, requires an additional wait state (one machine
cycle). The instruction set consists of 45% one-byte, 41% two-byte and 14% three-byte
instructions.
The SAA-XC886 CPU provides a range of debugging features, including basic stop/start,
single-step execution, breakpoint support and read/write access to the data memory,
program memory and Special Function Registers (SFRs).
Figure 5 shows the CPU functional blocks.
