117 / 127 page ![]() Document Feedback AS7038RB Functional Description Datasheet • PUBLIC DS000726 • v2-00 • 2021-Jun-02 126 │ 116 Addr: 0xa0 STATUS Bit Bit Name Default Access Bit Description 4 irq_fifothreshold 0 R_PUSH1 FIFO is almost full (as defined in fifo_threshold, usually 3/4) 3 irq_adc_threshold 0 R_PUSH1 The ADC value was above the programmed adc_threshold register setting 2 irq_ltf 0 R_PUSH1 LTF measurement is done. check LTFSTATUS (or ignore it) 1 irq_sequencer 0 R_PUSH1 All configured sequencer iterations have finished 0 irq_adc 0 R_PUSH1 ADC has finished The STATUS register shows the current state of the interface. Some bits in here can trigger an interrupt. An asserted bit can be cleared by writing a '1' to it - in case of irq_led_supply_low and irq_clipdetect, this also clears the underlying condition in the CLIPSTATUS and LEDSTATUS registers. The FIFO threshold interrupt cannot be cleared directly, but only by lowering the FIFO level. The FIFO overflow interrupt is sticky and must be cleared explicitly. STATUS2 (Address 0xa1) Figure 163: STATUS2 Register Addr: 0xa1 STATUS2 Bit Bit Name Default Access Bit Description 7:3 Not used 0 R_PUSH1 Not used 2 irq_ltf_threshold_high 0 R_PUSH1 The LTF value was above the programmed ltf_threshold_high register setting 1 irq_ltf_threshold_low 0 R_PUSH1 The LTF value was below the programmed ltf_threshold_low register setting |
