【0x11 : Sensor State】

Name:

SIN_STATE

Address:

0x11

Description:

This register indicates the state of each sensor.

1 : Switch-on.(Register “SIN” > Register “ON”)

0 : switch-off. (Register “SIN” < Register “OFF”)

【0x13, 0x15 : Detection Switch-On】

Name:

DETECT_ON

Address:

0x13, 0x15

Description:

This register indicates the transition from Off state to On state of 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 ONDET interrupt source register.

1: Detect On. 0: No detect.

【0x14 : Detection slider On】

Name:

DETECT_SLIDER_ON

Address:

0x14

Description:

SLIDER_ON: The value of this register is “1” when SLIDER is detected.

1: Detect On. 0: No detect.

SLIDER_CNT[6:0] : The detected amount of movement is shown in 2’s complement. The amount of

movement detected in order of SIN0→SIN1→SIN2→…→SIN7 is expressed by a positive value, and

the amount of the movement detected in a reverse order is expressed by a negative value. The

amount of the movement is 2 when center of gravity moves to the next sensor, and when center of

gravity comes between 2 sensors, the amount of the movement is 1. It loops when the range where the

detected amount of movement that can be shown is exceeded. The next of 63(0111111) become

-64(1000000).

【0x16, 0x18 : Detection Switch-Off】

Name:

DETECT_OFF

Address:

0x16, 0x18

Description:

This register indicates the transition from On state to Off state of 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 OFFDET interrupt source register.

1 : Detect Off. 0 : No detect.
