Table 10. Shared PTOE Segments
sysIO Standards
Each I/O within a bank is individually con
fi
gurable based on the V
CCO
and V
REF
settings. Some standards also
require the use of an external termination voltage. Table 12 lists the sysIO standards with the typical values for
V
CCO,
V
REF
and V
TT.
For more information on the sysIO capability, please refer to Lattice technical note number
TN1000,
