PRELIMINARY DATA SHEET
Fig. 7–5:
7.5.3. Stop
Disable all inputs and outputs (POL.ENA=0, POL.OE=0).
7.6. Operation of Port Wake Module
Fig. 7–6:
7.6.1. Reset
Neither the wake-up source register (WUS) nor the wake-up
pin mode registers (WPMx) are reset to a defined value by
any reset source.
7.6.2. Initialization
The corresponding ports must be configured normal in.
For every Wake Port, which shall generate a wake-up signal,
the trigger mode in the WPMx register has to be pro-
grammed. For every Wake Port, which shall not generate a
wake-up signal, the trigger mode in the WPMx register has to

selected by flag WSC.AST if a level triggered mode shall be
used. The whole register WUS has to be cleared.
7.6.3. Operation
The Port Wake Module can be operated by polling, it can
generate an interrupt (ISN WAPI) or it can be used to gener-
ate a wake-up signal to leave a power saving mode.
To use a level triggered mode of a Wake Port the RTC Mod-
ule and the Polling Module have to be configured to provide
