“Control” Sub Tab
The Register tab provides for direct control of the registers of the device.
The Control sub-tab allows
enabling and disabling
functionality in the part and also
controls the wait time multiplier
(WLONG).
Additionally, a list box provides
options for turning ON all parts
(All On) of the device or turning
OFF all parts (All Off) of the
device simultaneously.
•
Enable Register (0x00) – Provides the ON/OFF control of the device.
•
Check boxes are provided to allow selection of specific functions on the device:
1.
PON – Power on. Activates internal oscillator. When =0 device is in standby.
2.
AEN – ALS Enable. Writing a one (1) enables the ALS
3.
PEN – Proximity Enable. Writing a one (1) enables the proximity detection.
4.
WEN – Wait Enable. Writing a one (1) activates the wait timer.
5.
AIEN – ALS Interrupt Enable. Writing a one (1) enables the ALS interrupt.
6.
PIEN - Proximity Interrupt Enable. Writing a one (1) enables the Proximity interrupt.
•
WTIME (0x03) – Wait time in 2.4ms increments, unless the WLONG bit is set, in which case
the wait time is multiplied by 12. The number to the right is the computed WTIME. See the
ATIME note in the ALS Sub Tab description.
•
Config Register (0x0D) – Controls the wait time multiplication factor of x12.
1.
WLONG – Wait Long. When checked (=1) enables the wait multiplier.
