Register #1 Product ID Revision Register
Register address = 81h. This register contains information about product ID and product revision.
Register data value of current revision = 21h.
Register #2 Rate of Proximity Measurement
Register address = 82h.
Note
• If self_timed measurement is running, any new value written in this register will not be taken over until the mode is actualy cycled.
Register #3 LED Current Setting for Proximity Mode
Register address = 83h. This register is to set the LED current value for proximity measurement.
The value is adjustable in steps of 10 mA from 0 mA to 200 mA.
This register also contains information about the used device fuse program ID.

Fuse prog ID IR LED current value
Description
Fuse prog ID
Read only bits.
Information about fuse program revision used for initial setup/calibration of the device.
IR LED current value
R/W bits. IR LED current = Value (dec.) x 10 mA.
Valid Range = 0 to 20d. e.g. 0 = 0 mA , 1 = 10 mA, …., 20 = 200 mA (2 = 20 mA = DEFAULT)
LED Current is limited to 200 mA for values higher as 20d.
