Description
This pin is active high.
TRG = 1 o Normal proximity sensing operations
TRG = 0 o No operation (Default)
PWR = 0 o Power Shut Down (Default)
PWR = 1 and TRG = 0 o Standby
PWR = 1 and TRG = 1 o Active Operations
Number of LED Pulse per Burst = 16 x (1, 2, …, 16 times);
0x0 = 16-pulse, 0x1 = 32-pulse (Default), …, 0xE = 240-pulse,
0xF = 256-pulse
00 = 12.5kHz (Default), 01 = 25kHz, 10 = 50kHz, 11 = 100kHz;
Wave is fixed at 50% Duty Cycle
LED Burst Duration versus OFF period;
00 = 1:16, 01 = 1:64, 10 = 1:128 (Default) and 11 = 1:256
16 options of Comparator Threshold Setting;
0000 = 0.12V, 0001 = 0.17V, 0010 = 0.22V, 0011 = 0.27V,
0100 = 0.32V (Default), 0101 = 0.37V, 0110 = 0.42V, 0111 = 0.47V,
1000 = 0.52V, 1001 = 0.57V, 1010 = 0.62V, 1011 = 0.67V,
1100 = 0.72V, 1101 = 0.77V, 1110 = 0.82V, 1111 = 0.87V
Programmable Filter Register;
