TCE
At time T
High at the TCE input of the ODDR 3-state registers, enabling them for incoming
data. Since the TCE 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
valid-High at the T1 input of 3-state register 1 and is reflected on the TQ output at
