Comments
When Bit 0 is set,
the built in self-test
function is initiated.
Device offset trim
Configures the
outputs and the
format of the data
Determines CMOS
output drive
strength properties
On devices that
utilize global clock
divide, determines
which phase of the
divider output is
used to supply the
output clock;
internal latching is
unaffected
Sets the fine output
delay of the output
clock but does not
change internal
timing
Selects and/or
adjusts the VREF
