The counter settings are updated synchronously to the clock frequency of the
individual counters. Therefore, all counters are not simultaneously updated.
To reconfigure the PLL counters, follow these steps:
1. Assert the SCANCLKENA signal at least one SCANCLK cycle prior to shifting in the first

SCANCLKENA signal is deasserted to prevent inadvertent shifting of bits in the scan
chain. For Arria II GZ devices, after all 234 bits (top and bottom PLLs) or 180 bits
(left and right PLLs) have been scanned into the scan chain, the SCANCLKENA signal
is deasserted to prevent inadvertent shifting of bits in the scan chain.
