This value defines the number of TCLKs
(116.6 ns) separating AID symbols.
This value defines the number of TCLKs
(116.6 ns) separating AID symbol 0.
This value defines the number of TCLKs
(116.6 ns) separating data pulses for
Symbol 0 in low speed mode.
This value defines the number of TCLKs
(116.6 ns) separating data pulses for
Symbol 0 in high speed mode.
This value defines the duration of a transmit
pulse in OSC cycles (16.7 ns). This will
effectively determine the transmit spectrum
of the PHY.
This value defines the number of pulses
that will be driven onto the HRTXRX_N pin.
This value defines the number of pulses
that will be driven onto the HRTXRX_P pin.
