Global Shutter: Multiple Slope Integration
Use up to four different pixel reset voltages during multiple slope
operation in synchronous shutter mode. This is done by
uploading
KNEEPOINT_MSB/LSB/ENABLE before a new SS_START
pulse is applied.
Set bit KNEEPOINT_ENABLE high to do a pixel reset with a
lower voltage.
Set bits KNEEPOINT_MSB/LSB/ENABLE back to ‘0’ before the
SS_STOP pulse is applied. Every time an SS_START pulse is
applied, the integration time counter is reset.
The TIME_OUT signal cannot be used in multi-slope operation
to determine the location of the next SS_START or SS_STOP
pulse. External counters must be used for generating these
signals.
