The dynamic reconfiguration controller powers down only the selected CMU PLL.
The other CMU PLL is not affected.
Blocks Reconfigured in CMU PLL Reconfiguration Mode
Each transceiver block has two CMU PLLs—CMU0 PLL and CMU1 PLL.You can
reconfigure each of these CMU PLLs to a different data rate in this mode.

ALTGX MegaWizard Plug-In Manager Setup for CMU PLL Reconfiguration Mode
If you want to reconfigure the CMU PLL to another data rate, enable .mif generation
and set up the ALTGX MegaWizard Plug-In Manager, as described in the following
steps. The dynamic reconfiguration controller reconfigures the CMU PLL with the
new information stored in the .mif.
1. Select the Channel and Transmitter PLL reconfiguration option in the Modes
2. Provide the new data rate you want the CMU PLL to run at in the General screen.
The logical reference index of CMU0 PLL within a transceiver block is always the
complement of the logical reference index of CMU1 PLL.
