Input Control Register 4
| DSEL | Data Selection for Input Signal 0 (value1): The data input DXnA is selected. 1 (value2): The data input DXnB is selected. 2 (value3): The data input DXnC is selected. 3 (value4): The data input DXnD is selected. 4 (value5): The data input DXnE is selected. 5 (value6): The data input DXnF is selected. 6 (value7): The data input DXnG is selected. 7 (value8): The data input is always 1. |
| INSW | Input Switch 0 (value1): The input of the data shift unit is controlled by the protocol pre-processor. 1 (value2): The input of the data shift unit is connected to the selected data input line. This setting is used if the signals are directly derived from an input pin without treatment by the protocol pre-processor. |
| DFEN | Digital Filter Enable 0 (value1): The input signal is not digitally filtered. 1 (value2): The input signal is digitally filtered. |
| DSEN | Data Synchronization Enable 0 (value1): The un-synchronized signal can be taken as input for the data shift unit. 1 (value2): The synchronized signal can be taken as input for the data shift unit. |
| DPOL | Data Polarity for DXn 0 (value1): The input signal is not inverted. 1 (value2): The input signal is inverted. |
| SFSEL | Sampling Frequency Selection 0 (value1): The sampling frequency is fPERIPH. 1 (value2): The sampling frequency is fFD. |
| CM | Combination Mode 0 (value1): The trigger activation is disabled. 1 (value2): A rising edge activates DXnT. 2 (value3): A falling edge activates DXnT. 3 (value4): Both edges activate DXnT. |
| DXS | Synchronized Data Value 0 (value1): The current value of DXnS is 0. 1 (value2): The current value of DXnS is 1. |
