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 EP1SGX40 Stratix GX devices and 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 F780 package does
not support PLLs 11 and 12.
