3.4. Number of Calendar Pages

The Number of calendar pages parameter specifies the number of 16‑bit pages of in‑band flow control data that your 50G Interlaken IP core supports. The supported values are 1, 2, 4, 8, and 16.

Each 16-bit calendar page includes 16 in-band flow control bits. The application determines the interpretation of the in-band flow control bits. The IP core supports a maximum of 256 channels with in-band flow control.

If your design requires a different number of pages, select the lowest supported number of pages which is larger than the number required, and ignore any unused pages. For example, if your configuration requires three in-band flow control calendar pages, you can set Number of Calendar pages to 4 and use pages 3, 2, and 1 while ignoring page 0.

The default value of the Number of calendar pages parameter is 1.
