Data_Ready Status Bit ([7]=ALS/IR_RDY, [6]=PS_RDY, [5]=Solar_UV/UV_RDY)
7:5
Data Ready
Status
0 Data is NOT available to be used since power-on or last "clear".
The data is available after enable. Once this bit is set, the only 2 ways to clear it to 0 are to read this
1
register or set such sensing disable.
Interrupt Status Bits ([3]=ALS/IR_INTS, [2]=PS_Hi_INTS, [1]=PS_Lo_INTS)
0 No interrupt event has occurred since power-on or last "clear".
3:1 Interrupt Status
The data has exceeded the designated window limits defined by Threshold registers, and persist timer
1 _{is equal to the set Persist count. Once this bit is set, the only 2 ways to clear it to 0 are to read this}
register or set such sensing disable.
PS_Auto_Trim Interrupt Status Bit
0
PS_Auto_ Trim ^{0 No PS_Auto_Trim interrupt event has occurred since power-on or last “clear”.}
Interrupt Status
1 ^{The PS_Auto_Trim process has finished. Once this bit is set, the only 2 ways to clear it to 0 are to}
read this register or set PS_Auto_Trim_EN bit to 0.
