Similarly, transceiver channel 2 listens to CMU1 PLL of the transceiver block.
To direct the ALTGX_RECONFIG instance to dynamically reconfigure CMU0 PLL,
specify its logical reference index (the identity of a transmitter PLL). Similarly, to
direct the ALTGX_RECONFIG instance to dynamically reconfigure CMU1 PLL instead,
provide the logical reference index of CMU1 PLL. The allowed values for the logical
reference index of the CMU PLLs within a transceiver block are 0 or 1. Similarly, the
transmitter PLLs outside the transceiver block can also be assigned a logical reference
index value. For more information, refer to
