TUSB1046A-DCI: TUSB1046 configure EQ resistance

user5884264

Sorry to bother you, as shown below EQ control pin internal pull-up 35k ohm & internal pull-down 95k ohm & four level setting i only knows these messages, but when TUSB1046A default I2C to enable then the default of EQ control pin is internal pull-up or pull-down resistance?

Thank you!

Best regards,

All four-level inputs are latched on rising edge of internal reset with both internal and external resistors. In I2C mode. the default is 0000, it will overwrite the EQ value from GPIO mode.

Then the default value of EQx/SSEQx/DPEQx and I2C_EN is internal pull-up 35k ohm or pull-down 95k ohm?

All four-level inputs are latched on rising edge of internal reset. After tcfg_hd, the internal pull-up and pull-down resistors will be isolated in order to save power.
