devices.
The following modes are available for dynamically reconfiguring the Cyclone IV
transceivers:
■
■
The following sections describe each of these modes in detail.
The following modes are unsupported for dynamic reconfiguration:
■
■
■
You can dynamically reconfigure the following PMA controls for all supported
transceiver configurations channels as configured in the ALTGX instances:
■
■
■
■
You can use the analog reconfiguration feature to dynamically reconfigure the
transceivers channels setting in either the transmitter or the receivers in the PMA
blocks. You can update the PMA controls on-the-fly based on the desired input. You
can perform both read and write transaction separately for this analog reconfiguration
mode.
