TABLE 6 - REGISTER: PS_CONF3 DESCRIPTION
Command Bit Description Reserved 7 Default = 0 PS_AF 6 0 = auto mode; 1 = force mode 0 = no PS active force mode trigger, 1 = trigger one time cycle PS_FOR_Trig 5 VCNL36821S output one cycle data every time host writes in “1” to sensor. The state returns to “0” automatically PS_FORCENUM 4 0 = one detect cycle after trigger, 1 = two detect cycle after trigger Reserved 3 When use PS function, must write “1” PS_SP_INT 2 0 = disable, 1 = enable, PS sunlight light protect INT setting Reserved 1 : 0 Reserved
