Architectural Overview
The architecture of the C161U combines the advantages of both RISC and CISC
processors in a very well-balanced way. The sum of the features which are combined
result in a high performance microcontroller, which is the right choice not only for today's
applications, but also for future engineering challenges. The C161U not only integrates
a powerful CPU core and a set of peripheral units into one chip, but also connects the
units in a very efficient way. One of the four buses used concurrently on the C161U is
the XBUS, an internal representation of the external bus interface. This bus provides a
standardized method of integrating application-specific peripherals to produce derivates
of the standard C161U
