TMS570LS0432: nRST requirements

Ivan Liu Zhu
Prodigy 150 points
Part Number: TMS570LS0432

The datasheet of the uC establishes a start-up and timing sequence for nPORRST vs power lines.

Is there any requirement for nRST if it is not used? Can it be pulled-up safely to the same 3.3V line as the uC power supply? Is there any capacitor recommended in case of not using it?
