TUSB7320: PHYBoost

you can boost eye pattern by changing Swing with external EEPROM (0Eh to 11h). Pls see section 7.4.1.3 in datasheet

Thank you for your reply.

I have two questions.

1) Is the boost eye pattern accessible from PCI registers?

2) Is it possible to set the boost eye pattern with USB 2.0 (terminal name: USB_DM_DN2, USB_DP_DN2)?

1: from eeprom register, not PCI register.

2: sorry, boost eye can not do for USB2 from register, you can lower external resistor between R1EXT and R1EXTRTN to boost USB2 eye.

Thank you for your reply.

In 1), you answered that it is not a PCI register, but there is a description of the PCI register address in the above description, but is it different?
