State of Pins in Software Initiated Power Saving Modes
In the idle mode and power down mode, the port pins of the C508 have well defined
states which is listed in the following
Table 12
. The state of some pins also depends on
the location of the code memory (internal or external).
Table 12
In the power down mode of operation,
V
DD
can be reduced to minimize power
consumption. It must be ensured, however, that
V
DD
is not reduced before the power
down mode is invoked and the
V
DD
is restored to its normal operation level, before the
power down mode is terminated.
Table 13
gives a general overview of the entry and exit
procedures of the power saving modes.
