General Module Operation
This section provides information about the:

18.9.1
Input Selection
Each CCU6 input signal can be selected from a vector of four or eight possible inputs by programming the port
input select registers PISEL0 and PISEL2. This permits to adapt the pin functionality of the device to the
application requirements.
The output pins for the module output signals are chosen in the ports.
Note:
All functional inputs of the CCU6 are synchronized to f
CC6
before they affect the module internal logic.
The resulting delay of 2/f
CC6
and for asynchronous signals an additional uncertainty of 1/f
CC6
have to
be taken into account for precise timing calculation. An edge of an input signal can only be correctly
detected if the high phase and the low phase of the input signal are both longer than 1/f
CC6
.
