Different Dynamic Reconfiguration Modes Involved
1. Channel and CMU PLL reconfiguration mode—used for reconfiguring four
2. Central control unit reconfiguration mode—used for reconfiguring central control

regular transceiver channels and the CMU0 PLL (in GXBR0) from XAUI mode to
PCIe ×4 mode and vice versa.

unit logic used in bonded modes from XAUI mode to PCIe ×4 mode.
One .mif is required to move from XAUI mode to PCIe ×4 mode
Another .mif is required to revert back to XAUI mode from PCIe ×4 mode

Alternatively, you may use reduced .mif reconfiguration. Reduced .mifs are
generated using the altgx_diffmifgen.exe command. For more information, refer
to
“Reduced .mif Reconfiguration” on page
5–19.
Use this mode instead of channel reconfiguration with transmitter PLL
select mode because the central clock divider used for bonded modes is
only available in CMU0; therefore, you cannot use the CMU1 PLL as an
alternate TX PLL.
