Dynamic Reconfiguration Controller Port List
Table 3–2. Dynamic Reconfiguration Controller Port List (ALTGX_RECONFIG Instance) (Part 3 of 6)
Input/
Port Name
Output
This is a 2-bit wide signal. You can select this in the Error checks screen.
The advantage of using this optional port is that it allows you to reconfigure only the transmitter
portion of a channel, even if the channel configuration is duplex.
For a setting of:
rx_tx_duplex_sel
rx_tx_duplex_sel[1:0] = 2'b00—the transmitter and receiver portion of the
■
Input
[1..0]
channel is reconfigured.
rx_tx_duplex_sel[1:0] = 2'b01—the receiver portion of the channel is
■
reconfigured.
rx_tx_duplex_sel[1:0] = 2'b10—the transmitter portion of the channel is
■
reconfigured.
Analog Settings Control/Status Signals
This is an optional transmit buffer V
number of settings varies based on the transmit buffer supply setting and the termination
resistor setting on the TX Analog screen of the ALTGX MegaWizard Plug-In Manager.
The width of this signal is fixed to 3 bits if you enable either the Use 'logical_channel_address'
port for Analog controls reconfiguration option or the Use same control signal for all the
channels option in the Analog controls screen. Otherwise, the width of this signal is 3 bits per
channel.
The following shows the V
termination.
