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.

Figure 3 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 40 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 resources, 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.
