mode_chg_reg

R/W

0

It is used to reset the full sensor array and exposure

address

when

critical

operation

mode

is

changed(useful only that register “flag” is set to 1

and reset of the full sensor array and exposure

address will start till the first new frame is readout

after register “flag” is set to 1) .

It will be reset by the same mechanism that flag

register be reset.
