【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.
