Power Management
The C167CS provides several means to control the power it consumes either at a given
time or averaged over a certain timespan. Three mechanisms can be used (partly in
parallel):
• Power Saving Modes switch the C167CS into a special operating mode (control via
• Clock Generation Management controls the distribution and the frequency of
• Peripheral Management permits temporary disabling of peripheral modules (control
The on-chip RTC supports intermittent operation of the C167CS by generating cyclic
wakeup signals. This offers full performance to quickly react on action requests while the
intermittent sleep phases greatly reduce the average power consumption of the system.

instructions).
Idle Mode stops the CPU while the peripherals can continue to operate.
Sleep Mode and Power Down Mode stop all clock signals and all operation (RTC may
optionally continue running). Sleep Mode can be terminated by external interrupt
signals.
internal and external clock signals (control via register SYSCON2).
Slow Down Mode lets the C167CS run at a CPU clock frequency of
for prescaler operation) which drastically reduces the consumed power. The PLL can
be optionally disabled while operating in Slow Down Mode.
External circuitry can be controlled via the programmable frequency output FOUT.
via register SYSCON3).
Each peripheral can separately be disabled/enabled. A group control option disables
a major part of the peripheral set by setting one single bit.
