Power Saving Modes
Two power down modes are available, the Idle Mode and the Power Down Mode.
The bits PDE, PDS and IDLE, IDLS select the Power Down mode or the idle mode, respectively. If
the Power Down mode and the idle mode are set at the same time, Power Down takes precedence.
Table 15
gives a general overview of the power saving modes.
Table 15
Entering and Leaving the Power Saving Modes
In the Power Down mode of operation,
V
CC
can be reduced to minimize power consumption. It must
be ensured, however, that
V
CC
is not reduced before the Power Down mode is invoked, and that
V
CC
is restored to its normal operating level, before the Power Down mode is terminated. The reset
signal that terminates the Power Down mode also restarts the oscillator. The reset should not be
activated before
V
CC
is restored to its normal operating level and must be held active long enough
to allow the oscillator to restart and stabilize (similar to power-on reset).
