7.3.4.3

4 outputs

When only 4 outputs are used, the pixel data is placed on the outputs as detailed Figure 40. 4

bursts of 128 pixels happen in parallel on the data outputs. This means that one complete row

is read out in four bursts. The time needed to read out one row is 4x longer compared to when

16 outputs are used. Only channel 1, 5, 9 and 13 are being used in this mode, so the

remaining channels can be turned off by setting the correct bits in the register with addresses

80-82. Turning off these channels will reduce the power consumption of the chip.

The amount of rows that will be read out can be set in the register. By default there are 1088

rows being read out.

7.3.4.4

2 outputs

When only 2 outputs are used, the pixel data is placed on the outputs as detailed in Figure 41.

2 bursts of 128 pixels happen in parallel on the data outputs. This means that one complete

row is read out in 8 bursts. The time needed to read out one row is 8x longer compared to

when 16 outputs are used. Only channels 1 and 9 are being used in this mode, so the

remaining channels can be turned off by setting the correct bits in the register with addresses

80-82. Turning off these channels will reduce the power consumption of the chip.

The amount of rows that will be read out can be set in the register. By default 1088 rows are

read out.
