Other Parts Discussed in Thread: TMS320C6747, TMS320C6745, TPS650061


I read an article: "Powering the TMS320C6745 and TMS320C6747 with the TPS650061" and I don't understand why are using the precision resistors: 

R2 - 47.5k

R7 - 475k 

R9 - 47.5k

Can I use this option ?

R2 - 47k - 5%

R7 - 470k - 5%

R9 - 47k- 5%

On Figure2. TPS650061 Schematic Diagram  -  pin 1 (MR) directly connected to the VODC (1.2V). I want to use this pin for manual reset. 

For this i must be connected  MR-pin with button through the resistor  to the VODC (1.2V) or to the VIN(5V)  ? 

Pull up resistor must be 470k or 47k ?
