9.7.9 Multi ROI mode (Multi Region of Interest)
In this trigger mode, up to 5 ROIs located on one image can be output by one trigger input.
By using this mode, the data stream can be smaller. Each ROI can be overlapped.
Please note that if the accumulated data size is bigger than the data size of 1 frame, the
frame rate will be reduced.
As explained in section 9.3.3, a partial scan mode is associated with ROI and in the case of
figure 51, the start line of ROI 2 and the end line of ROI 4 would define a partial scan area.

Note: 1. Trigger mode can be set by writing ID value in register 0xA040.
2. In trigger modes from ID 0x09 to ID 0x12, if trigger mode is changed, set “Acquisition Stop”
and then set continuous mode(ID 0x00) first and change to required trigger mode. For
instance, it is not possible to change directly from ID 0x09 sequential EPS mode to 0x11 EPS
delayed readout mode.
