N 45 postamblephaseinvert Connects to the phaseinvertctrl
port of the clock phase select (for
the DQS enable control block) to
select between the non-inverted

Use this clock phase select block
to level the postamble

This setting allows the phase
output from the delay chain to be
inverted to gain additional
phases.
