Keyscan Stop [Function Mode: 5]
MSM9223 stops a key scanning when function mode 5 are selected.
To select this mode, the only mode data (M0 to M2) is needed.
The actual time lag range between receipt of the keyscan stop command and the ceasing of
scanning is 2.4ms to 3.6ms
[Input Data Format]
Input Data
: 3 bits
Mode Data
: 3 bits
Switch Data Output [Function Mode: 6]
MSM9223 output the switch data when function mode 6 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.
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)
