TMG3992 − Register Description

Wait Time Register (WTIME 0x83)

The WTIME controls the amount of time in a low power mode

between Proximity and/or ALS cycles. It is set 2.78ms

increments unless the WLONG bit is asserted in which case the

wait times are 12× longer. WTIME is programmed as a 2’s

complement number. Upon power up, the wait time register is

set to 0xFF.

Figure 48:

Wait Time Register

Note(s):

1. The wait time register should be configured before AEN and/or PEN is asserted.

2. During any Proximity and/or ALS cycle, the wait state, depicted in the functional block diagram, is entered. For example, Proximity

only, Proximity and ALS, or ALS only cycles always enter the WAIT state and are separated by the time defined by WTIME.
