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
(see definition in the AC Characteristics section).
Figure 3
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 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
module CAN1, so the default XBUS resources are compatible with the C167CR.
