To reconfigure the transceiver channel or CMU PLL, you must configure the required
settings for the transceiver channel or CMU PLL in the ALTGX MegaWizard Plug-In
Manager and compile the ALTGX instance. The dynamic reconfiguration controller
requires that you write these configured settings through the .mif into the transceiver
channel or CMU PLL (using the write_all and reconfig_data[15:0] signals). The
maximum possible size of the .mif is 59 words. Each word contains legal register
settings of the transceiver channel stored in 16 bits. reconfig_address_out[5:0]
provides the address (location) of the 16-bit word in the .mif.

You can store these .mifs in on-chip or off-chip memory.
Store the .mif in on-chip or off-chip memory and connect it to the dynamic
reconfiguration controller, as shown in
When applying a .mif in the user design, be sure to:

Note to
(1) Each word in the .mif is 16 bits wide.
Use the RAM: 1-PORT megafunction to instantiate a memory block.
Choose the size of the memory block based on the size of the .mif generated.
