|
|
* **Detailed Description :**
|
|
*
|
|
* This header file for pin control is based on the most common configuation options
|
|
* curenty awailable for modern hardware.
|
|
* Depending of the used Chip, some function may vary or be unawailable.
|
|
* Please take a minute to go and explore the according Chips pin.c file to see woh each function
|
|
* is implmented.
|
|
*
|
|
* @todo
|
|
* - 03.11.2021 : MAybe find a way to link the awalabe uart channnels with the awailable pins for that USART channel
