The following table describes the
DNA_PORTE2 primitive pins. Connect all inputs and outputs to the design to ensure proper
operation. All functions are synchronous to the CLK input.
| Pin | Type | Width | Description |
|---|---|---|---|
| CLK | Input | 1 | User clock input. |
| DIN | Input | 1 | User data extension input pin. |
| DOUT | Output | 1 | DNA output pin. Transitions on the rising edge of CLK, LSB first. |
| READ | Input | 1 | Read DNA by pulsing High to parallel load 96 eFUSE bits into shift register (see Table 2). |
| SHIFT | Input | 1 | Active-High shift enable. Shift requires
Read=0. |
