3.10
The C161S 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):
•
•
•
The on-chip RTC supports intermittent operation of the C161S by generating cyclic
wake-up 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.
Data Sheet
Power Saving Modes switch the C161S into a special operating mode (control via
instructions).
Idle Mode stops the CPU while the peripherals can continue to operate.
Power Down Mode stops all clock signals and all operation (RTC may optionally
continue running).
Clock Generation Management controls the distribution and the frequency of
internal and external clock signals (control via register SYSCON2).
Slow Down Mode lets the C161S 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.
Peripheral Management permits temporary disabling of peripheral modules (control
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.
