Write enable output
Write enable indicates the time when active samples (Y,
U and V) are present
Timing relation (see Fig.6) depending on write enable
select signal (WES) in status register; to adapt to
different external video memories
The number of output samples is a multiple of 4
The write enable output sequence is a copy of the write
enable input sequence of the previous line (see Fig.6)
with a shift of one line
The last line in field is not processed.
