first select line. The first select line goes high as soon as a Sync_y pulse occurs
together with a rising edge of Clock_y. On the next rising edge of Clock_y, the next
row is selected, unless Sync_y is still active. In figure 15, a short Sync_y pulse
makes sure that the first row is selected during 1 period of Clock_y.
Once a line is selected, it needs to stabilize first of all, which is called the row
blanking time, and secondly the pixels need to be read out. Figure 15 shows the
principle.
Once the information of the selected line is stable the addressing of the pixels can
start. This is done by means of a Sync_x and a Clock_x pulse in the same way as the
Y-addressing. The Sync_x pulse downloads the address in the address register into
the shift register and connects the first block of 16 columns to the 16 outputs.
In fact on chip is a 32-output bus instead of 16, but on the rising edge of Clock_x the
first 16 columns of the bus are connected to the output stages. On the falling edge of
Clock_x, the last 16 columns of the selected bus are connected to the output stages.
