Power Management
Besides the basic power-save (power-reduction) modes Idle mode and Power down
mode, the C161U offers a number of additional power management features, which can
be selectively used for effective power reduction. Refer to Table 1.

Note: Peripherals Management enables the user to control (via software) the clock of

selected peripherals. Refer to register SYSCON 3.
Description
The system is fully operational. All clocks and
peripherals are set and enabled, as determined
by software. Full power consumption.
The CPU runs slower. The oscillator runs at a
lower frequency; the clock is divided by a
programmable factor (1...32). Peripherals
management is possible; incl. PLL On/Off.
Refer to register SYSCON 2.
When the processor has no active tasks to
perform, it enters Idle mode by the IDLE
command. All peripherals remain powered and
clocked, however, peripherals management is
possible. For detailed description see
Chapter 19.1, "Idle Mode".
The program stops execution and turns off the
clocks for:
• almost the entire chip, but RTC, or
• the entire chip.
Refer to register SYSCON 1.
The program stops execution (instruction
PWRDN) and turns off the clocks for the CPU
and for all peripherals; ports optionally.
The whole clock system is stopped.
