the OQ output at time T
and resetting ODDR Register 2, reflected at the OQ output at time T
(no change at the OQ output in this case).
OCE
At time T
High at the OCE input of the ODDR registers, enabling them for incoming data. Since
the OCE signal is common to all ODDR registers, care must be taken to toggle this
signal between the rising edges and falling edges of C as well as meeting the register
setup-time relative to both clock edges.
At time T
