Hello,

Here are my comments,

• JTAG_TCK – tied to GND if not used
• JTAG_TDI/TDO/TMS – These terminals can be left unconnected if JTAG is not required.
• CLKRUN_EN – you have it as NC, please set 0 = Clock run support disabled or 1 = Clock run support enabled
• EXT_ARB_EN – you have it as NC, please set 0 = Internal arbiter enabled or 1 = External arbiter enabled
• XIO2001 Rx lines – Doble check the caps are not duplicated in PCH Tx line side.

Regards,
Roberto

Hi Sirs,

Thanks for your reply.

We have two questions on these control pin

• CLKRUN_EN – you have it as NC, please set 0 = Clock run support disabled or 1 = Clock run support enabled
• EXT_ARB_EN – you have it as NC, please set 0 = Internal arbiter enabled or 1 = External arbiter enabled

Base on our design, could you share how and when need set H/L?

Have default setting?
