TMS320F28388D: Routing 3 GPIO inputs to eCAP using input X-BAR

Dear support team,

I need to capture 3 tachometer inputs with TMS320F28388D board.

The schematic assigned each tachometer inputs to GPIO64, GPIO65, GPIO66.

So, I'd like to route those signals to eCAP#1, #2, #3, in DSP, like this.

I thought there are multiple input XBAR resources in TMS320F28388D.

But, I could configure no more than ONE input XBAR with SysConfig tool.

Could you suggest me the way to route 3 GPIO inputs (64, 75, 66) to 3 eCAP ?

Thank you in advance.
