Power Management
The XC161 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 XC161 into a special operating mode (control via
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.
Clock Generation Management
controls the distribution and the frequency of
internal and external clock signals. While the clock signals for currently inactive parts
of logic are disabled automatically, the user can reduce the XC161’s CPU clock
frequency which drastically reduces the consumed power.
External circuitry can be controlled via the programmable frequency output FOUT.
Peripheral Management
permits temporary disabling of peripheral modules (control
via register SYSCON3). Each peripheral can separately be disabled/enabled.
The on-chip RTC supports intermittent operation of the XC161 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.
