Assume that you have enabled tx_vodctrl in the ALTGX_RECONFIG MegaWizard
Plug-In Manager to reconfigure the V
the write transaction to reconfigure the V
If you want to read the existing values from a specific channel connected to the
ALTGX_RECONFIG instance, observe the corresponding byte positions of the PMA
control output port after the read transaction is complete.
For example, if the number of channels controlled by the ALTGX_RECONFIG
instance is two, tx_vodctrl_out is 6 bits wide (tx_vodctrl_out[2:0] corresponds to
channel 1 and tx_vodctrl_out[5:3] corresponds to channel 2).
