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
(dqsenablein signal at the DQS
enable control block).
This setting allows the phase
output from the delay chain to be
inverted to gain additional
phases.
