Coef new,
Lane 1
[5]
When set to 1, indicates that new link partner
coefficients are available to send. The LT logic
starts sending the new values set in 0xD4[7:0] to
the remote device. When set to 0, continues
normal operation. This bit self clears.
This override of normal operation can only
occur if 0xD0[16] (
Ovride LP Coef enable
)
has the value of 1. If 0xD0[16] has the value of 0,
this register field (0xD1[5]) has no effect.
Register bit 0xD1[4] refers to Lane 0. This bit is
the equivalent of register 0xD1[4] for Lane 1.
