8 / 17 page ISL76683 8 FN7697.7 March 24, 2014 Submit Document Feedback Register Set There are eight registers that are available in the ISL76683. Table 1 summarizes the available registers and their functions. TABLE 1. REGISTER SET ADDR (HEX) REGISTER NAME BIT(S) FUNCTION NAME FUNCTIONS/DESCRIPTION 00 Command 7 Enable 0: disable ADC-core 1: enable ADC-core 6 ADCPD 0: Normal operation 1: Power-down Mode 5 Timing_Mode 0: Integration is internally timed 1: Integration is externally sync/controlled by I2C host 4 Reserved 3:2 Mode<1:0> Selects ADC work mode 0: Diode1’s current to unsigned 16-bit data 1: Diode2’s current to unsigned 16-bit data 2: Difference between diodes (I1 - I2) to signed 15-bit data 3: reserved 1:0 Width<1:0> Number of clock cycles; n-bit resolution 0: 216 cycles 1: 212 cycles 2: 28 cycles 3: 24 cycles 01 Control 7 Ext_Mode Always set to logic 0. Factory use only. 6 Test_Mode Always set to logic 0 5 Int_Flag 0: Interrupt is cleared or not yet triggered 1: Interrupt is triggered 4 Reserved Always set to logic 0. Factory use only. 3:2 Gain<1:0> Selects the gain so range is 0: 0 to 1000 lux 1: 0 to 4000 lux 2: 0 to 16000 lux 3: 0 to 64000 lux 1:0 Int_Persist <1:0> Interrupt is triggered after 0: 1 integration cycle 1: 4 integration cycles 2: 8 integration cycles 3: 16 integration cycles 02 Interrupt Threshold HI 7:0 Interrupt Threshold HI High byte of HI interrupt threshold. Default is 0xFF 03 Interrupt Threshold LO 7:0 Interrupt Threshold LO High byte of the LO interrupt threshold. Default is 0x00 04 LSB_Sensor 7:0 LSB_Sensor Read-Only data register that contains the least significant byte of the latest sensor reading. 05 MSB_Sensor 7:0 MSB_Sensor Read-Only data register that contains the most significant byte of the latest sensor reading. 06 LSB_Timer 7:0 LSB_Timer Read-Only data register that contains the least significant byte of the timer counter value corresponding to the latest sensor reading. 07 MSB_Timer 7:0 MSB_Timer Read-Only data register that contains the most significant byte of the timer counter value corresponding to the latest sensor reading. |
