TUSB4020BI: unused pins?

Part Number: TUSB4020BI

Hi,

I do not use the pins whose names I have written below.

What I should do when I do not use these pins is not specified in the pin table in the datasheet.

What should I do with these pins?

PWRCTL1/BATEN1    *I use the downstream port1 for USB communication, but I don't need these pins because I don't use a power switch.

OVERCUR1z     *I use the downstream port1 for USB communication, but I don't need these pins because I don't use a power switch.

SMBUSz       *I will not use SMBUS or I2C.
