ml9227 Oki Semiconductor, ml9227 Datasheet - Page 16

• Manufacturer Part Number: ml9227
• Description: 27-bit Duplex/triplex Vfd Controller/driver With Digital Dimming, Adc And Key Scan
• Manufacturer: Oki Semiconductor

• ML9227 output the switch data when function mode 6 is selected.
• To select this mode, the only mode data (M0 to M2) is needed.
• When ML9227 recieves this mode, the DATA I/O pin is changed to an output pin.
• 29-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.
• R1 = 0, implies Right rotation of the knob (Clockwise)
• R1 = 1, implies Left rotation of the knob (Counter Clockwise)
• Contact Count bits are Q1 (LSB) to Q3 (MSB)
