Data Sheet
20.5
This module especially serves for power management support, controlling dynamically
the operation and thus the power consumption of the different peripherals on PD Bus
and XBUS. In each situation (eg. several system operating modes, standby, etc.) only
those peripherals may be kept running which are required for the respective functionality.
All others can be switched off. It also allows the operation control of whole groups of
peripherals.
Peripheral’s operation is disabled or enabled by controlling the specific clock input. This
function also is supported in idle and/or slow down mode.
The Real Time Clock (RTC) may be fed by a separate clock driver, so it can be kept
running even in power down mode.
While a peripheral is disabled its output pins remain in the state they had at the time of
disabling.
Note: In contrast to the peripheral management of Infineon’s 16x family the registers of
a disabled module are not accessable. Only the clock control register of the
platform peripheral is accessable. Note, the register access is not compatible to
the C167CS.
