2. I2C Interface
The VCNL4010 contains seventeen 8 bit registers for operation control, parameter setup and result buffering. All registers are
accessible via I2C communication. Figure 13 shows the basic I2C communication with VCNL4010.
The built in I2C interface is compatible with all I2C modes (standard, fast and high speed).
I2C H-level range = 1.7 V to 5 V.
Please refer to the I2C specification from NXP for details.

Device Address
Register Addresses
The VCNL4010 has a fix slave address for the host
programming and accessing selection. The predefined 7 bit
I2C bus address is set to 0010 011 = 13h. The least
significant bit (LSB) defines read or write mode. Accordingly
the bus address is set to 0010 011x = 26h for write, 27h for
read.
VCNL4010 has seventeen user accessible 8 bit registers.
The register addresses are 80h (register #0) to 90h
(register #16).
REGISTER FUNCTIONS
Register #0 Command Register
Register address = 80h
The register #0 is for starting ambient light or proximity measurements. This register contains 2 flag bits for data ready indication.

Description
config_lock
Read only bit. Value = 1
als_data_rdy
Read only bit. Value = 1 when ambient light measurement data is available in the result registers. This bit
will be reset when one of the corresponding result registers (reg #5, reg #6) is read.
prox_data_rdy
Read only bit. Value = 1 when proximity measurement data is available in the result registers. This bit will
be reset when one of the corresponding result registers (reg #7, reg #8) is read.
als_od
R/W bit. Starts a single on-demand measurement for ambient light. If averaging is enabled, starts a
sequence of readings and stores the averaged result. Result is available at the end of conversion for
reading in the registers #5(HB) and #6(LB).
prox_od
R/W bit. Starts a single on-demand measurement for proximity.
Result is available at the end of conversion for reading in the registers #7(HB) and #8(LB).
als_en
R/W bit. Enables periodic als measurement
prox_en
R/W bit. Enables periodic proximity measurement
selftimed_en
R/W bit. Enables state machine and LP oscillator for self timed measurements; no measurement is
performed until the corresponding bit is set
Note
• With setting bit 3 and bit 4 at the same write command, a simultaneously measurement of ambient light and proximity is done. Beside als_en
and/or prox_en first selftimed_en needs to be set. On-demand measurement modes are disabled if selftimed_en bit is set. For the
selftimed_en mode changes in reading rates (reg #4 and reg #2) can be made only when b0 (selftimed_en bit) = 0. For the als_od mode
changes to the reg #4 can be made only when b4 (als_od bit) = 0; this is to avoid synchronization problems and undefined states between
the clock domains. In effect this means that it is only reasonable to change rates while no selftimed conversion is ongoing.
