Description
Reference
This option is enabled by default when you select the
Channel and TX PLL select/reconfig option. The value
on reconfig_address_out[5:0] indicates
the address associated with the words in the .mif,
which contains the dynamic reconfiguration
instructions. The dynamic reconfiguration controller
automatically increments the address at the end of
each .mif write transaction.

When high, this optional output status signal indicates
that the address to be used in the .mif write
transaction cycle has changed. This signal gets
asserted when the .mif write transaction is completed
(the busy signal de-asserted).

When asserted, this optional control signal resets the
reconfig_address_out (current
reconfiguration address) to 0.
