TUSB216-Q1: SCL/SDA Internal PULLUP/PULLDOWN Value For I2C mode

Part Number: TUSB216-Q1

Dear Team,

1. We'd like to clarify the TUSB216-Q1 SCL1/SDA1internal PU/PD value.

Please help to confirm if below cognition is right ?

I2C mode (default)
SCL1: 500K ohm PD
SDA1: 500K ohm PU

Non I2C mode (default)
CD: 500K ohm PD
SDA1: 1.8M ohm PD

2.IF SDA1/SCL1 both don't use that means PIN3 & PIN4 without connection on schematic for use case,
is that still normal for application ?


Thank you.
