Notes
1. All VDDD pins are internally connected.
2. All VSSD pins are internally connected.
3. DLO is a command flag from register 4 (see Section “Command registers”).
4. SA is the stand-alone/microcontroller operated pin (pin 43). DI11, NSD, DI2, QU1, QU0 and MS0 are command flags
to control the operation of the device. For more information see Section “Controlling the GDIN”.
