Description
Fuse prog ID
IR LED current value
Read only bits.
Information about fuse program revision used for initial setup/calibration of the device.
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.
