The <=1Gbps reads:

<=1Gbps

Set PHTW=H’01020100
Set PHTW=H’01010172
Set PHTW=H’01570170
Set PHTW=H’01060171
Set PHTW=H’01110172

Is it clear why theres a difference here?

What doc is that? Mine (R19UH0172EJ0054 Rev.0.54) says:

Set PHTW=H’01020100
Set PHTW=H’01910170
Set PHTW=H’01020171
Set PHTW=H’01110172
