Switch Data Output [Function Mode: 6]

• ML9228 output the switch data when function mode 6 is selected.

• To select this mode, the only mode data (M0 to M2) is needed.

• When ML9228 recieves this mode, the DATA I/O pin is changed to an output pin.

• 30-bit switch data come out from the DATA I/O pin synchronizing with the rise edge of the clock.

• When the CS pin is set at the low level, the DATA I/O pin returns to an input pin.

• Contact Count bits are Q1 (LSB) to Q3 (MSB)
