Digital Inputs (DI) Information
Pull up / Pull Down Configuration:
- By default all the digital inputs are pulled LOW. The Digital Input Pull-Up Enable pin (DI_Hi_Pull_EN) is used to configure the pull on the digital inputs.
- For Example, in FCE 2.1, Setting PTE14 HIGH will pull up the digital inputs 1-6. Refer datasheet for more Info.
- Each digital input is equipped with signal conditioning and protection features, including Voltage Limiting, Voltage Filtering, and Current Limiting, to safeguard the MCU.
- Make sure the input voltage is between the threshold range mentioned above for HIGH and LOW values.
