SEMICONDUCTOR TECHNICAL DATA
ImageMOS
The
Global DOVA Register; Table 28
performs a final
offset adjustment in analog space prior to the ADC. The
6-bit register uses its MSB to indicate positive or nega-
tive offset. Each bit value changes the offset value by 4
LSB code levels hence giving an offset range of +/-124
LSB. As an example, to program an offset of +92 LSB,
the binary representation of +23
d
i.e. 010111
b
should
be loaded.
13.4 Sensor Interface Block
13.4.1 Sensor Output Control
The sensor output control registers define how the win-
dow of interest is captured and what data is output from
the MCM20027.
The
Capture Mode Control Register; Table 29
, defines
how the data is captured and how the data is to be pro-
vided at the output..
Setting the
cms
bit will stop the current output data
stream at the end of the current frame. Unsetting this bit
(
cms
= 0
b
) will resume the output of the frame stream.
The MCM20027 is in CFRS in default. The user may
use this bit to capture data in the CFRS mode and/or
SFRS while using the SYNC pin. The SYNC pin triggers
a single frame of data to be output from the device in the
