FPC402: SFP rate selection(RS0/RS1) by OUT_B

Part Number: FPC402

Dear team,

Our application need to independently control RS0/RS1. Based on datasheet, we can use OUT_B[3:0] and GPIO[3:0] to implement.

I would like to double confirm connection, which one is correct? or both way are ok. Thanks.

RS0 connected to OUT_B

RS1 connected to GPIO

 Or

RS0 connected to GPIO

RS1 connected to OUT_B
