[signal] | [I/O] | [Description] |
ENCSEL | I | This signal is used to set master/slave using the CSEL signal (pin 28). |
|
| Pins A and C Open: Sets master/slave by the MSTR signal |
|
| without using the CSEL signal. |
|
| Short: Sets master/slave using the CSEL signal. |
|
| The MSTR signal is ignored. |
