TMS320F280049: Questions on accuracy of F280049's internal OSC

Part Number: TMS320F280049

Hi expert,

My customer would like to use F280049's internal OSC and want to check below details with you.

1. When MCU is supplied with a stable DC source at the right value, if there is any fixed relation between internal OSC's accuracy and temperature?

2. Do we have any method to compensate OSC's error in this device? How?

3. If using an internal OSC as main clock, what will be the influence of inaccuracy on PWM output and SCI communication?

Thanks

Sheldon
