External feedback is available in PLLs 5 and 6.
This single-ended external output is available from the g0 counter for PLLs 11 and 12.
These four counters and external outputs are available in PLLs 5 and 6.
This connection is only available on EP1S40 and larger Stratix devices. For example, PLLs 5 and 11 are adjacent and
PLLs 6 and 12 are adjacent. The EP1S40 device in the 780-pin FineLine BGA package does not support PLLs 11
and 12.
