A/D Data Output [Function Mode: 7]
• MSM9223 output the A/D data when function mode 7 is selected.
• To select this mode, the only mode data (M0 to M2) is needed.
• When MSM9223 recieves this mode, the DATA I/O pin is changed to an output pin.
• 48-bit A/D data come out from the DATA I/O pin synchronizeing with the rise edge of the
• When the CS pin is set at the low level, the DATA I/O pin returns to an input pin.
