Enable Sense Pin.
1 = Enable corresponding key
0 = Disable corresponding key
6.9 Address 0x0C: De-Bounce
The value is from 1 to 7. Set this parameter to prevent key output bouncing. Key will react slower
with less chance happening bouncing when set this value higher.
6.10 Address 0x0D: Plus Times
The value is from 15 to 127. The captures data will be more stable and key react slower if set this
value higher.
6.11 Address 0x0E: Sensor Cycle
The value is from 3 to 15. The captures data will be more stable and key react slower if set this
value higher.
6.12 Address 0x0F: Calibration Delay
The value is from 7 to 63. It defines how long chip will do re-calibration process again.
This bit is valid if “Auto” bit is set to “1”.

B-Change:
This bit will be set to “1” if any key is pressed.
It will be cleared to “0” if all key are released.
This bit will be set to “1” if any key status is changed.
It will be cleared to “0” if no key status is changed whether key is
pressed or not.
