All rights reserved. 14.Jul.2016 Rev.002 www.rohm.com TSZ22111・15・001 【 0x1B : State of interrupt from the peripherals】 Name: STATE_INT Address: 0x1B Description: This register shows the peripheral which issues an interrupt to MPU. 1 : Interrupt is. 0 : Interrupt is not. Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0x1B PWM3 PWM2 PWM1 PWM0 WDT - AFE I2C R/W 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. Indicates whether the IC is in calibration or not. 1 : In calibration. 0 : Not in calibration The required time for calibration.:About 140 msec. Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0x1C - - - - - - - CALIB R/W - - - - - - - R Initial val. 0 0 0 0 0 0 0 0 【 0x1D : Sensor State】 Name: STATE_SIN Address: 0x1D Description: This register indicates the state of each sensor 1 : Switch-on. (Register ‘SIN_DATA’ > Register ‘TH_ON’) 0 : Switch-off. (Register ‘SIN_DATA’ < Register ‘TH_OFF’) Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0x1D - - - SIN4 SIN3 SIN2 SIN1 SIN0 R/W - - - R R R R R Initial val. 0 0 0 0 0 0 0 0 【 0x1E : Read register for operation check of IC】 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 are equal, MPU and I/F are operating normally. The required time to copy to this register from the write register for operation check : About 20usec.
