15 The CM3605 is an entirely analog part. However, it requires quite a bit of
16 software logic to interface a host operating system.
18 This ALS and proximity sensor was one of the very first deployed in mobile
19 handsets, notably it is used in the very first Nexus One Android phone from

35 Connected to the POUT (proximity sensor out) line. The edge
36 detection must be set to IRQ_TYPE_EDGE_BOTH so as to detect
37 movements toward and away from the proximity sensor.
