Functional Description
Chapter 3 provides an overview of the XC87x functional description.
3.1
Processor Architecture
The XC87x 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 XC87x CPU uses a 2-clock machine
cycle. This allows fast access to ROM or RAM memories without wait state. The
instruction set consists of 45% one-byte, 41% two-byte and 14% three-byte instructions.
The XC87x 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 6 shows the CPU functional blocks.
