CH[3:0] : Effective channel ：
This indicates which button is dominant.
SIMUL : Button effective ：
This indicates that the effective channel corresponds to a valid button press according to the thresholds. 1 : On. 0 : Off.
CONTINU : A push and hold is effective ：
Indicates that the button was pressed and held for more than push/hold judgment time. 1 : On. 0 : Off.

CH7
The sensor output that converts to 10bit. Scaling, offsets and filtering (when enabled) are applied.
The most significant 8 bits are presented to the software with this register.
Indicates the duration of the gesture in number of internal clocks.
The count is a clock set with 0xE4(GES_CLK).
It is possible to count up to 0～4095 clocks.
