It is necessary to clear this flag to detect. The corresponding clear register is 0xF5 [7]. 1 : Detect Off. 0 : No detect. Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0x17 SLIDER_OFF - - - - - - - R/W R R R R R R R R Initial val. 0 0 0 0 0 0 0 0 【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. Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0x19 SW7_CONT SW6_CONT SW5_CONT SW4_CONT SW3_CONT SW2_CONT SW1_CONT SW0_CONT 0x1B MAT_CONT - - - KEY_CONT[3] KEY_CONT[2] KEY_CONT[1] KEY_CONT[0] R/W R R R R R R R R Initial val. 0 0 0 0 0 0 0 0 【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 Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0x1C E_CALIB - - - - - INTVL CALIB R/W R - - - - - R R Initial val. 0 - - - - - 0 0 【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. Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0x1E RACT[7] RACT[6] RACT[5] RACT[4] RACT[3] RACT[2] RACT[1] RACT[0] R/W R R R R R R R R Initial val. 0 0 0 0 0 0 0 0 |
