Functional Description
3.1
Processor Architecture
The XC866 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 XC866 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 XC866 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 SFRs.
