This signal is applicable only in the dynamic reconfiguration modes
grouped under the Channel and TX PLL select/reconfig option.
This is a 16-bit word carrying the reconfiguration information. It is
stored in a .mif that you must generate. The ALTGX_RECONFIG
instance requires that you provide reconfig_data [15:0]on
every .mif write transaction using the write_all signal.
This port is available for selection only in .mif-based transceiver
channel reconfiguration modes.

This signal is available when you select data rate division in
transmitter mode. Based on the value you set here, the divide-by
setting of the local divider in the transmitter channel gets modified.
The legal values for this port are:
2’b00 = Divide by 1
2’b01 = Divide by 2
2’b10 = Divide by 4
2’b11 = Not supported
This signal is available when you select data rate division in
transmitter mode. You can read the existing local divider settings of
a transmitter channel at this port. The decoding for this signal is
listed below:
2’b00 = Division of 1
2’b01 = Division of 2
2’b10 = Division of 4
2’b11= Not supported
At this port you specify the identity of the transmitter PLL you want
to reconfigure. You can also specify the identity of the transmitter
PLL that you want the transceiver channel to listen to. When you
enable this signal, the value set at this signal overwrites the
logical_tx_pll value contained in the .mif. The value at this port
must be held at a constant logic level until reconfiguration is done.
If you want to use the logical_tx_pll_sel port only under
some conditions and use the logical_tx_pll value contained in
the .mif otherwise, enable this optional logical_tx_pll_sel_en
port. Only when logical_tx_pll_sel_en is enabled and set to 1
does the dynamic reconfiguration controller use
logical_tx_pll_sel to identify the transmitter PLL. The value at
this port must be held at a constant logic level until reconfiguration
is done.
This signal goes high to indicate that the dynamic reconfiguration
controller has finished writing all the words of the .mif. The
channel_reconfig_done signal is automatically de-asserted at
the start of a new dynamic reconfiguration write sequence. This
signal is applicable only in channel and CMU PLL reconfiguration
and channel reconfiguration with transmitter PLL select modes.
