Preliminary
Annex 1.1.7. BiasHandshake Register
This register sets the times shown in below:
1) Between the suspend start and the verification of the TpBias for the other device.
2) Between the detection of the other device’s TpBias and the providing stop of its own TpBias.
3) Between the resume start and the providing stop of its own TpBias.
Do not set ”0” for the bias_handshake field in this register.

Set the time of the bias_handshake.
The calculation is;
(Setting value) x 125us.
Annex 1.1.8. BiasFilterTime Register
This register is used to set the time between the detection of the other device’s TpBias and the setting of the
Bias bit on the PHY register.
Do not set ”0” for the bias_filter_time field in this register.
