WTIME Register (Address 0x83)

If wait is enabled (WEN = “1” register 0x80), each new measurement is started based on WTIME. It is

necessary for WTIME to be sufficiently long for spectral integration and any other functions to be

completed within the period. The device will warn the user if the timing is configured incorrectly. If

WTIME is too short, then SP_TRIG in register STATUS4 (ADDR: 0xBC

) will be set to “1”.
