3. Cyclone IV Dynamic Reconfiguration
Cyclone
®
IV GX transceivers allow you to dynamically reconfigure different portions
of the transceivers without powering down any part of the device. This chapter
describes and provides examples about the different modes available for dynamic
reconfiguration.
You can use the ALTGX_RECONFIG and ALTPLL_RECONFIG controller instance to
reconfigure the physical medium attachment (PMA) controls, physical coding
sublayer (PCS), multipurpose phase locked loops (PLLs), and general purpose PLLs.
This chapter contains the following sections:
