Hi,
Current TPS6598x configuration tool is using HD3SS460 as default settings, but it is not matching with TUSB1046 control pins, see below for detail.
1. GPIO2= POL will be no problem
2. GPIO0= AMSEL= CTL0
HD3SS460 AMSEL: “H” for 4ch alternative mode DP
TUSB1046 CTL0: “L” for 4ch alternative mode DP
Suppose to configure GPIO0 as USB3.x event
3. GPIO1= EN= CTL1
HD3SS460 EN: “H” for USB or alternative mode DP, “M” for 2ch USB + 2ch AM DP and “L” for shutdown
TUSB1046 CTL1: “L” for USB 3.1 only and “H” for alternative mode DP and 2ch USB + 2ch AM DP
Suppose to use GPIO4, DP Hot plug detection for CTL1
Could you please confirm my idea or any comments?
Thanks and Best regards,
Tiger
