LED2VAL: LED2 Digital Sample Value Register (Address = 2Ah, Reset Value = 0000h)
D23 D22 D21 D20 D19 D18 D17 D16 D15 D14 D13 D12
LED2VAL[23:0]
D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
LED2VAL[23:0]
This register contains the digital value of the latest LED2 sample converted by the ADC. The ADC_RDY signal
goes high each time that the contents of this register are updated. The host processor must readout this register
before the next sample is converted by the AFE.
Bits D[23:0] LED2VAL[23:0]: LED2 digital value
This register contains the digital value of the latest LED2 sample converted by the ADC. The
ADC_RDY signal goes high each time that the contents of this register are updated. The
host processor must readout this register before the next sample is converted by the AFE.
ALED2VAL: Ambient LED2 Digital Sample Value Register (Address = 2Bh, Reset Value = 0000h)
D23 D22 D21 D20 D19 D18 D17 D16 D15 D14 D13 D12
ALED2VAL[23:0]
D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
ALED2VAL[23:0]
This register contains the digital value of the latest LED2 ambient sample converted by the ADC. The ADC_RDY
signal goes high each time that the contents of this register are updated. The host processor must readout this
register before the next sample is converted by the AFE.
Bits D[23:0] ALED2VAL[23:0]: LED2 ambient digital value
This register contains the digital value of the latest LED2 ambient sample converted by the
ADC. The ADC_RDY signal goes high each time that the contents of this register are
updated. The host processor must readout this register before the next sample is converted
by the AFE.
LED1VAL: LED1 Digital Sample Value Register (Address = 2Ch, Reset Value = 0000h)
D23 D22 D21 D20 D19 D18 D17 D16 D15 D14 D13 D12
LED1VAL[23:0]
D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
LED1VAL[23:0]
This register contains the digital value of the latest LED1 sample converted by the ADC. The ADC_RDY signal
goes high each time that the contents of this register are updated. The host processor must readout this register
before the next sample is converted by the AFE.
Bits D[23:0] LED1VAL[23:0]: LED1 digital value
This register contains the digital value of the latest LED1 sample converted by the ADC. The
ADC_RDY signal goes high each time that the contents of this register are updated. The
host processor must readout this register before the next sample is converted by the AFE.
