Functional Description
The architecture of the C164CI combines advantages of both RISC and CISC
processors and of advanced peripheral subsystems in a very well-balanced way. In
addition the on-chip memory blocks allow the design of compact systems with maximum
performance.
The following block diagram gives an overview of the different on-chip components and
of the advanced, high bandwidth internal bus structure of the C164CI.
Note: All time specifications refer to a CPU clock of 25 MHz
(see definition in the AC Characteristics section).

Block Diagram
The program memory, the internal RAM (IRAM) and the set of generic peripherals are
connected to the CPU via separate buses. A fourth bus, the XBUS, connects external
resources as well as additional on-chip resoures, the X-Peripherals (see Figure 3).
The XBUS resources (XRAM, CAN) of the C164CI can be enabled or disabled during
initialization by setting the general X-Peripheral enable bit XPEN (SYSCON.2). Modules
that are disabled consume neither address space nor port pins.
