D. Key data output
This command puts the pin in the output mode and causes the pin to output the scanned switch data.
The DI/O pin outputs 42-bit switch data at the rise of a clock.
When the
CS pin goes high, the DI/O pin enters the output mode.
“R1, R2, R3 = 0” means turning a control knob clockwise.
“R1, R2, R3 = 1” means turning a control knob counterclockwise.
Contact count bits are Q11(LSB) to Q13(MSB), Q21(LSB) to Q23(MSB), and Q31(LSB) to Q33(MSB).
