SE4400 Integration Guide
To enter Mode D, halt the acquisition of the 8-bit pixel data. The recovery time for
this mode can vary from 66 ms down to 33 ms, depending on how near the exit of
Mode D is to the end of the frame (if it occurs immediately prior to the end of the
frame, the recovery time is 33 ms). While Mode D is shown as drawing the same
current as Mode E, Mode D saves power because the host draws less current by
not reading the pixel data.
In Mode E images are continuously acquired. It has a recovery time of zero
because the last frame in memory can be used.
