Si114x Sample Data Structure.

The SI114X_IRQ_SAMPLE Data is populated within a low-level interrupt handler.

sequence is not directly from the Si113x/4x, but rather, the low-level interrupt handler can increment a rolling counter whenever a sample is made. sequence is provided a convenience to upper software layers.

timestamp is not from the Si113x/4x directly. The low_level interrupt handler is expected to use any convenient time reference associated with the sample. This will allow the upper layers to have a sense of time.

irqstat , vis , ir , ps1 , ps2 , ps3 and aux are directly from the Si113x/4x. Beginning with irqstat , these members are roughly in the order of I2C Registers 0x21 to 0x2D.

Note
ps1 , ps2 and ps3 are not used by the Si1132.
Si1132 reports UVINDEX in aux .
