Read (MM2S) channel: When configured as Genlock Master, the channel does not skip or repeat the frames. It outputs the current frame number on mm2s_frame_ptr_out. It does not monitor the frame pointer values on mm2s_frame_ptr_in. Genlock Slave should follow the Genlock Master with a predetermined frame delay value set in its *frmdly_stride[28:24].
Write (S2MM) channel: When configured as Genlock Master, the channel does not skip or repeat the frames. It outputs the current frame number on s2mm_frame_ptr_out. It does not monitor the frame pointer values on s2mm_frame_ptr_in. Genlock Slave should follow the Genlock Master with a predetermined frame delay value set in its *frmdly_stride[28:24].
