In this method, the PMA controls are written into all the channels connected to the
dynamic reconfiguration controller. Therefore, to write to a specific channel:
1. Retain the stored values of the other active channels using a read transaction.
2. Set the new value at the bits corresponding to the specific channel.
3. Perform a write transaction.
For example, assume that the number of channels controlled by the
ALTGX_RECONFIG instance is two, tx_vodctrl in this case is 6 bits wide
(tx_vodctrl[2:0] corresponds to channel 1 and tx_vodctrl[5:3] corresponds to
channel 2). Follow these steps:
1. If you want to dynamically reconfigure the PMA controls of only channel 2 with a

values from tx_vodctrl_out[5:0]. Take tx_vodctrl_out[2:0] and provide this
value in tx_vodctrl[2:0] to the write in channel 1. By doing so, channel 1 is
overwritten with the same value.
