TCS3430 − Register Description
CFG3 Register (0xAB)
Figure 36:
CFG3 Register
Note(s):
1. SAI does not modify any register bits directly, it rather uses the interrupt signal to turn OFF the oscillator.
0xAB: CFG3
Field Name Reset Type Description
7 INT_READ_CLEAR 0 RW
If this bit is set, all flag bits in the STATUS register will be
reset whenever the STATUS register is read over I
2
C.
6:5 RESERVED 0 RW Reserved. Set to 0.
4SAI0RW
Sleep After Interrupt. Power down the device at the end
of the ALS cycle if an interrupt has been generated.

The way to “wake up” the device from SAI-sleep is by
clearing the interrupt register 0x93.
3:0 RESERVED 0 RW Reserved. Set to 0.

TCS3430 − Register Description
AZ_CONFIG Register (0xD6)
Figure 37:
AZ_CONFIG Register
Note(s):
1. On average mode 1 is faster, but in the worst case, mode 0 is faster.
INTENAB Register (0xDD)

INTENAB Register
0xD6: AZ_CONFIG
Field Name Reset Type Description
7AZ_MODE 0RW
0: Always start at zero when searching the best offset
value
1: Always start at the previous (offset_c) with the
auto-zero mechanism

0x7F RW
Run autozero automatically every nth ALS iteration

0xDD: INTENAB
Field Name Reset Type Description
7 ASIEN 0 RW Writing '1' to this bit enables ASAT interrupt.
6:5 RESERVED 0 RW Reserved
4 AIEN 0 RW Writing '1' to this bit enables ALS interrupt.
