Notes to
(1) In this waveform example, you want to write to only the transmitter portion of the channel.
(2) In this waveform example, the number of channels controlled by the dynamic reconfiguration controller (the ALTGX_RECONFIG instance) is two

The read transaction in Method 3 is identical to that in Method 2. Refer to

This is the slowest method. You have to write all the PMA settings for all channels
even if you may only be changing one parameter on the channel. Altera recommends
using the logical_channel_address method for time-critical applications.
For each method, you can additionally reconfigure the PMA setting of both
transmitter and receiver portion, transmitter portion only, or receiver portion only of
the transceiver channel. For more information, refer to
