【0x17 : Detection slider Off】
Name:
DETECT_SLIDER_OFF
Address:
0x17
Description:
It is set when IC detects that the slider is in the off state. It is necessary to clear this flag to detect. The
corresponding clear register is 0xF5 [7].
1 : Detect Off. 0 : No detect.

【0x19, 0x1B : Detection continued touch】
Name:
DETECT_CONT
Address:
0x19, 0x1B
Description:
This register indicates the detection of continued touch for every switch.
Since SW 0-7 supports multiple presses, each switch has bit recognition. And the matrix key does not
support multiple detection, so matrix switch is indicated by 1 bit for ON detection (MAT) and 4 bits(KEY
switch). Logical OR of each SW and MAT will be CONTDET interrupt source register.
1 : Detect continued touch. 0 : No detect.

【0x1C : State of IC】
Name:
STATE
Address:
0x1C
Description:
This register indicates the state of IC.
CALIB : Indicates whether the IC is in calibration or not.
1: In calibration 0: Not in calibration
INTVL : Indicates whether the IC is in Intermittent Operation or not.
1: Intermittent Operation 0: Not in Intermittent Operation
E_CALIB : When the calibration fails for three consecutive times, it is set.
1: Calibration Error 0: No Error

【0x1E : Read register for operation check of MPU】
Name:
RACT
Address:
0x1E
Description:
This register is a read register for operational check of the IC. The value written to the write register for
operation check (Address is 0xFE) is copied to this register. If the write value and the read value is equal,
MPU and I/F are operating normally.
