Command Bit Description Reserved 7 : 6 (0 : 0), reserved Reserved 5 : 4 (0 : 0), reserved PS_HD 3 0 = PS output is 12 bits, 1 = PS output is 16 bits Reserved 2 Default = 0 (0 : 0) = interrupt disable, (0 : 1) = trigger by closing, (1 : 0) = trigger by away, PS_INT 1 : 0 (1 : 1) = trigger by closing and away
TABLE 6 - REGISTER: PS_CONF3 DESCRIPTION PS_CONF3 COMMAND CODE: 0x04_L (0x04 DATA BYTE LOW)
Command Bit Description Reserved 7 Default = 0 Reserved 6 : 5 (0 : 0) PS_SMART_PERS 4 0 = disable; 1 = enable PS smart persistence PS_FOR 3 0 = active force mode disable (normal mode), 1 = active force mode enable 0 = no PS active force mode trigger, 1 = trigger one time cycle PS_FOR_TRIG 2 The VCNL3040 conducts a single measurement every time the host writes a “1” to this bit. The state returns to “0” automatically Reserved 1 : 0 (0 : 0) Rev. 1.2, 08-Jul-2019
