When bonding ×N channels in a Basic (PMA Direct) drive mode configuration, you
can reset all bonded channels simultaneously.

Only channels in Basic (PMA Direct) drive ×4 functional mode with no PLL_L/R.
As shown in
drive functional ×4 mode with no PLL_L/R, follow these reset steps:
1. After power up, assert pll_powerdown for a minimum of t
2. When the transmitter PLL locks, as indicated by the pll_locked signal going high
between markers 1 and 2).
(marker 3), the transmitter is ready to accept parallel data from the FPGA fabric
and subsequently transmitting serial data reliably.
