THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 VCNL4000 Vishay Semiconductors Fully Integrated Proximity and Ambient Light Sensor with Infrared Emitter and I2C Interface Register #5 and #6 Ambient Light Result Register Register address = 85h and 86h. These registers are the result registers for ambient light measurement readings. The result is a 16 bit value. The high byte is stored in register #5 and the low byte in register #6. Register #7 and #8 Proximity Measurement Result Register Register address = 87h and 88h. These registers are the result registers for proximity measurement readings. The result is a 16 bit value. The high byte is stored in register #7 and the low byte in register #8. Register #9 Proximity Measurement Signal Frequency Register address = 89h. TABLE 5 - AMBIENT LIGHT RESULT REGISTER #5 Bit 7 Bit 6Bit 5Bit 4Bit 3 Bit 2Bit 1Bit 0 Description Read only bits. High byte (15:8) of ambient light measurement result TABLE 6 - AMBIENT LIGHT RESULT REGISTER #6 Bit 7 Bit 6Bit 5Bit 4Bit 3 Bit 2Bit 1Bit 0 Description Read only bits. Low byte (7:0) of ambient light measurement result TABLE 7 - PROXIMITY RESULT REGISTER #7 Bit 7 Bit 6Bit 5Bit 4Bit 3 Bit 2Bit 1Bit 0 Description Read only bits. High byte (15:8) of proximity measurement result TABLE 8 - PROXIMITY RESULT REGISTER #8 Bit 7 Bit 6Bit 5Bit 4Bit 3 Bit 2Bit 1Bit 0 Description Read only bits. Low byte (7:0) of proximity measurement result TABLE 9 - PROXIMITY MEASUREMENT SIGNAL FREQUENCY #9 Bit 7 Bit 6Bit 5Bit 4Bit 3 Bit 2Bit 1Bit 0 N/A Proximity frequency Description Bit 0 and 1 Proximity frequency R/W bits. Setting the proximity IR test signal frequency. The proximity measurement is using a square IR signal as measurement signal. Four different values are possible: 00 = 3.125 MHz 01 = 1.5625 MHz 02 = 781.25 kHz (DEFAULT) 03 = 390.625 kHz |
