TABLE 2. WRITE ONLY REGISTERS

Mode3 is a sequential Mode0 and Mode1 with an internal

REGISTER

FUNCTIONS/

subtract function (Diode1 - Diode2).

DESCRIPTION

TABLE 6. PHOTODIODE SELECT MODE; BITS 2 AND 3

b1xxx_xxxx

bx1xx_xxxx

sync_iic

clar_int

Writing a logic 1 to this address bit ends

the current adc-integration and starts

another. Used only with External Timing

Mode.

Writing a logic 1 to this address bit

clears the interrupt.

BITS 3:2

0:0

0:1

MODE

Mode0. ADC integrates or converts Diode1 only. Current

is converted to an n-bit unsigned data.*

Mode1. ADC integrates or coverts Diode2 only. Current is

converted to an n-bit unsigned data.*

1:0

MODE3. A sequential Mode0 then Mode1 operation. The

Command Register 00(hex)

The Read/Write command register has five functions:

1:1

difference current is an (n-1) signed data.*

No operation.

(1) Enable; Bit 7.This function either resets the ADC or

enables the ADC in normal operation. A logic 0 disables

ADC to reset-mode. A logic 1 enables adc to normal

operation.

TABLE 3. ENABLE

* n = 4, 8, 12,16 depending on the number of clock cycles

function.

(5) Width; Bits 1 and 0. This function determines the number

of clock cycles per conversion. Changing the number of

clock cycles does more than just change the resolution of

OPERATION

Disable ADC-core to reset-mode (default)

Enable ADC-core to normal operation

the device. It also changes the integration time, which is the

period the device’s analog-to-digital (A/D) converter samples

the photodiode current signal for a Lux measurement.

(2) AdcPD; Bit 6. This function puts the device in a power

down mode. A logic 0 puts the device in normal operation. A

logic 1 powers down the device.

Control Register 01(hex)

The Read/Write control register has three functions:

(3) Timing Mode; Bit 5. This function determines whether the

integration time is done internally or externally. In Internal

Timing Mode, integration time is determined by an internal

dual speed oscillator (fosc), and the n-bit (n = 4, 8, 12,16)

counter inside the ADC. In External Timing Mode, integration

time is determined by the time between two consecutive

(1) Interrupt flag; Bit 5. This is the status bit of the interrupt.

The bit is set to logic high when the interrupt thresholds have

been triggered, and logic low when not yet triggered. Writing

a logic low clears/resets the status bit.

Internal Timing Mode. Integration time is internally

timed determined by fosc, REXT, and number of clock

cycles.

External Timing Mode. Integration time is externally

timed by the I2C host.

(2) Range/Gain; Bits 3 and 2. The Full Scale Range can be

adjusted by an external resistor Rext and/or it can be

adjusted via I2C using the Gain/Range funtion. Gain/Range

has four possible values, Range(k) where k is 1 through 4.

Table 9 lists the possible values of Range(k) and the

(4) Photodiode Select Mode; Bits 3 and 2. This function

controls the mux attached to the two photodiodes. At Mode0,

the mux directs the current of Diode1 to the ADC. At Mode1,

the mux directs the current of Diode2 only to the ADC.

resulting FSR for some typical value R EXT resistors. When

Gain/Range is set to Range1 or Range2, the fosc runs at

327kHz. When Gain/Range is set to Range3 or Range4 fosc

runs at twice the rate at 655kHz. The automatic fosc

adjustment feature improves signal-to-noise ratio for low Lux

measurements.
