TSL2771 − Register Set

Configuration Register (0x0D)

The configuration register sets the wait long time.

Configuration Register

Proximity Pulse Count Register (0x0E)

The proximity pulse count register sets the number of proximity

pulses that will be transmitted. When proximity detection is

enabled, a proximity detect cycle occurs after each ALS cycle.

PPULSE defines the number of pulses to be transmitted at a

62.5-kHz rate.

Note(s): The ATIME register will be used to time the interval

between proximity detection events even if the ALS function is

disabled.
