TCS3720 − Register Overview

IPTAT Register (Address 0x1A)

Figure 27:

IPTAT Register

Enable Register (Address 0x80)

Figure 28:

ENABLE Register

Preset each applicable registers and its bits as per required

operation before activating PON. After PON is set, it is required

to wait 100μs settling time and then enable AEN and /or PEN.

In order to modify register configurations during operation, it

is required to set AEN=PEN=PON=0 firstly to avoid any

unexpected behavior or corrupted ALS and proximity results.

Disabling PON resets the device state machine, but all the

set the PON bit and wait 100μs settling time, and then enable

AEN and /or PEN to re-activate the corresponding

functionalities.
