Hi experts,
My customer has created a board using the TMS320F28034. Let me check a few things about the device.
Can I assume that the value of the internal pullup resistor of the TMS320F28034 is as follows? (The value is calculated for GPIO from "7.6 Electrical Characteristics" in the datasheet.)
Max: 41.25kΩ
Typ: 23.57kΩ
Min: 16.09kΩ
They have attached a feedback resistor (Rf=1MΩ) to the circuit of the external crystal, but is the feedback resistor inside the microcontroller?
If they add an external feedback resistor, is there any possibility that something will go wrong?
Best regards,
O.H
