The following table lists the IDDRE1 attributes.
| Attribute | Values | Default | Type | Description |
|---|---|---|---|---|
| DDR_CLK_EDGE |
OPPOSITE_EDGE SAME_EDGE SAME_EDGE_PIPELINED |
OPPOSITE_EDGE | String | Sets the IDDRE1 mode of operation with respect to clock edge. |
| IS_C_INVERTED | 0 or 1 | 0 | Bit | Sets a local clock inversion for C input when 1. |
| IS_CB_INVERTED | 0 or 1 | 0 | Bit | Sets a local clock inversion for CB input. When IS_CB_INVERTED = 1, C and CB must be driven by the same global clock buffer. When IS_CB_INVERTED = 0, CB must be driven by the same global clock buffer through an inverter. |
