Video Port FIFO
1-7
Overview
SPRU629
For 8/10-bit raw video, the FIFO is split into channel A and B, as shown in
Figure 1–3. Each FIFO is clocked independently with the channel A FIFO
receiving data from the VDIN[9–0] half of the bus and the channel B FIFO
receiving data from the VDIN[19–10] half of the bus. Each channel’s FIFO has
a separate write pointer and read register (YSRCx). The FIFO configuration
is identical for TSI capture, but channel B is disabled.
