Dynamic Reconfiguration Reset Sequences
Reset Sequence in PLL Reconfiguration Mode
Cyclone IV Device Handbook, Volume 2
When using dynamic reconfiguration in data rate divisions in PLL reconfiguration or
channel reconfiguration mode, use the following reset sequences.
Use the example reset sequence shown in
reconfiguration controller to change the data rate of the transceiver channel. In this
example, PLL dynamic reconfiguration is used to dynamically reconfigure the data
rate of the transceiver channel configured in Basic ×1 mode with the receiver CDR in
automatic lock mode.

signals. The pll_configupdate signal is asserted (marker 1) by the
ALTPLL_RECONFIG megafunction after the final data bit is sent out. The
pll_reconfig_done signal is asserted (marker 2) to inform the
ALTPLL_RECONFIG megafunction that the scan chain process is completed. The
ALTPLL_RECONFIG megafunction then asserts the pll_areset signal (marker
3) to reset the transceiver PLL.
