System Control Unit CSCU is used to control system specific tasks such as reset control
or power management (see previous Chapter "Power Reduction Modes") within an on-
chip system build around the Infineons Cell-Based Core C166. The power management
features of the CSCU provide effective means to realize standby conditions for the
system with an optimum balance between power reduction, peripheral operation and
system functionality. Additionally, the CSCU controls the modes and operation of Real
Time Clock RTC.
Summary of Features and Functions
CSCU is characterized by the following functions:

In the following paragraphs a functional overview of the different blocks and submodules
of the System Control Unit is presented.
XBUS Peripheral Configuration Block
In the C161U, XBUS peripherals can be separately switched on or off by programming
the XPERCON register. If switched off, the respective peripheral is not visible, meaning,
that its address space and its functional pins are not occupied.
