Register address map
The TSL3301
LF contains seven registers as defined in Table 2. Data in these registers may be written to or
read from using the
REGWrite
and
REGRead
commands. Three registers control the gain of the
analog-to-digital converters (ADC). Three other registers allow the offset of the system to be adjusted. Together
the gain and offset registers are used to maximize the achievable dynamic range.

The offset registers are 8-bit sign-magnitude values and the gain registers are 5-bit values. The programmed
offset correction is applied to the sampled energy, and then the gain is applied. (i.e., the gain will affect the offset
correction.) These registers allow the user to maximize the dynamic range achievable in the given system.
The last register is the mode register. Bits in this register select the sleep mode as well as options for multichip
arrays and production testing. Note that test and multichip options do not apply to the 8-pin packaged device.
Users should always write zeros into the production test and multichip control bits.
