Could you please address tha below queries regarding the subject part number:
1. Please let us know what are the IIH (Input Current High) and IIL (Input Current Low) values for the GPIOs of TM4C1231E6PM.
2. Regarding VBAT pin of TM4C1231E6PM. Please let us know whether there is any battery reversal protection in built to the microcontroller, if not suggest any part to use along with battery for supplying VBAT pin.
3. In datasheet of TM4C1231E6PM, it is mentioned as "The Hibernation module power source is determined dynamically", this means no need to use external switching circuit to switch in between external VDD and Battery supply on VBAT pin. Please confirm on this.
Soonest response would be appreciated!!!
