MR
Setting bit MR0 to logic high will initiate a CS7654 master reset equivalent to executing an ex-
ternal reset using the RESET pin. All registers will be placed in their default state, and the down-
load of any external EPROM present on the secondary I2C bus will be initiated. The bit is self-cleared.

Logic high indicates even field of interline-transfer CCD. Logic low indicates odd field of inter-
line-transfer CCD. This bit provides a course means of synchronizing to the field rate.
NODEV
Logic high indicates that the addressed slave device on the secondary I2C bus did not respond.
