The used words level of the input FIFO.
The detected sample count of the video streams excluding blanking.
The detected line count of the video streams F0 field excluding blanking.
The detected line count of the video streams F1 field excluding blanking.
The detected sample count of the video streams including blanking.
The detected line count of the video streams F0 field including blanking.
The detected line count of the video streams F1 field including blanking.
The contents of the vid_std signal.
Start of frame sample register. The sample and sub-sample upon which the SOF
occurs (and the sof signal triggers):
■
■
Start of frame line register. The line upon which the SOF occurs measured from
the rising edge of the F0 vertical sync.
Number of cycles of vid_clk (refclk) before refclk_div signal triggers.
When bit 1 is asserted, the status update interrupt has triggered.
When bit 2 is asserted, the stable video interrupt has triggered.
The interrupts stay asserted until a write of 1 is performed to these bits.
Bits 0–1 are the subsample value.
Bits 2–15 are the sample value.
