TUSB1310A: RESETN

Part Number:TUSB1310A

Hi Sir 

The issue is when the system power on and reset TUSB1310A again ,Sometimes TUSB1310A UPLI_CLK will change from 60MHz to 75MHz ,It's not correct 

May I know could we reset TUSB1310A again when power on ,due to the datasheet show "The RESETN is used only at power on"
