Functional Description
The architecture of the C167CS 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 C167CS.
Note: All time specifications refer to a CPU clock of 33 MHz
Figure 3
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
The XBUS resources (XRAM, CAN) of the C167CS can be individually enabled or
disabled during initialization. Register XPERCON selects the required modules which
are then enabled by setting the general X-Peripheral enable bit XPEN (SYSCON.2).
Modules that are disabled consume neither address space nor port pins.
Note: The default value of register XPERCON after reset selects 2 KByte XRAM and
