AM1808 VPIF Frame Interrupt Timing

Hi,

I have questions about AM1808 VPIF interrupt.

The question is about frame interrupt.

I understand that the frame interrupt will be generated at the begining of frame.

But I want to know the timing of frame interrupt assertion.

1.Is frame interrupt timing same as VSYNC signal?

2.Does VPIF generate the frame interrupt at the timing of VSYNC rising-edge detection?

In TRM(spruh82a) page.1738 " 35.2.12.2 Field/Frame Interrupts to CPU ", it is written as follows:

//////////////////////////////////////////////////////////////////////////

The timing of the interrupt from the VPIF module is different from the timing of the V-sync.

//////////////////////////////////////////////////////////////////////////

but in page.1739, it is written as follows:

//////////////////////////////////////////////////////////////////////////

The interrupt signal from the VPIF is asserted when the vertical synchronization signal is received

//////////////////////////////////////////////////////////////////////////

So, I'm confusing.

best regards,

g.f.
