4.1
The timing and control circuit can be programmed to sub-sam-
ple pixels in the display window vertically, horizontally or both,
with an aspect ratio of 2:1 as illustrated in figure 16.

To program the sensor in 2:1 Sub-sampling the HSub-
SamEn bit in the MCFG1 register should to be set to a
logic one.
Setting the HSubSamEn bit in the MCFG1 to a logic
one will switch on the horizontal sub-sampling, while
setting the VSubSamEn bit in the MCFG1 register will
switch on the vertical sub-sampling.
Sub-sampling cannot be used with interlace readout
mode.
When using horizontal sub-sampling Pclk is divided
by 2. The active time of Hsync is the same in sub-
sampled and non sub-sampled mode.
sub-sampling does not increase frame rate.
