TMD2772/ TMD2772WA − Register Description

Proximity Time Register (0x02)

The Proximity Time Register controls the integration time of the

proximity ADC in 2.73 ms increments. Time is expressed as a 2’s

complement number. It is recommended that this register be

programmed to a value of 0xFF (1 integration cycle).

Figure 35:

Proximity Time Register

Wait Time Register (0x03)

Wait time is set in 2.73 ms increments unless the WLONG bit is

asserted in which case the wait times are 12

x longer. WTIME is

programmed as a 2’s complement number.

Note(s):

1. The Proximity Wait Time Register should be configured before PEN and/or AEN is/are asserted.
