OFDDRTCPE is a dual data rate (DDR) D flip-flop with clock enable (CE) and asynchronous preset and clear whose output is enabled by a 3-state buffer. It consists of a dual data rate flip-flop (FDDRCPE) and a 3-state output buffer (OBUFT). The data output (O) of the flip-flop is connected to the input of the output buffer (OBUFT). The output of the OBUFT is connected to an OPAD or IOPAD. When the active-Low enable input (T) is Low, output is enabled and the data on the flip-flop s Q output appears on the OBUFT s O output. When the asynchronous PRE is High and CLR is Low, the O output is preset High. When CLR is High, O is set Low. Data on the D0 input is loaded into the flip-flop when PRE and CLR are Low and CE is High on the Low-to-High C0 clock transition. Data on the D1 input is loaded into the flip-flop when PRE and CLR are Low and CE is High on the Low-to-High C1 clock transition. When T is High, outputs are high impedance (Off). When CE is Low and T is Low, the outputs do not change. The flip-flops are asynchronously cleared with Low outputs when power is applied. (Source: XACT Libraries Guide, Xilinx Corporation, 2001.)
