- It is possible to read the pin status using the Pin_Read() API.
- When the Pin is driven Low, there is a Strong low signal on the Pin and the API Pin_Read() will return a zero.
- However, when a logic one is written using the API Pin_Write(), the pin is connected the Drain of the internal MOSFET and it is open. This means the value returned by the API Pin_Read() is determined by what voltage appears on the pin. A pull up provided on this pin will give a logic high.
