The core provides an option to program sets of two or four Info packets. The packets are transmitted to the Sink once per every video frame or 8192 cycles.

To change an Info packet during transmission, follow these steps:

  1. Disable Audio (because a new Info packet means a new audio configuration). The disable audio also flushes the internal audio buffers.
  2. To program the DisplayPort Source, see Programming the DisplayPort Source.
