EN_TEMP: 1 = temperature channel is in use, 0 = temperature channel is not in use
EN_DIAG_A: 1 = enables diagnostics on Active Light channel A, 0 = disables the diagnostics
EN_DIAG_B: 1 = enables diagnostics on Active Light channel B, 0 = disables the diagnostics
EN_CH_A: 1 = Active Light channel A is enabled (TIA + Filter), 0 = Active Light channel A is
completely switched off to reduce current consumption
EN_CH_B: 1 = Active Light channel B is enabled (TIA + Filter), 0 = Active Light channel B is
completely switched off to reduce current consumption
EN_CH_C: 1 = ambient light channel C is in use, 0 = ambient light channel C is not in use
EN_CH_D: 1 = ambient light channel D is in use, 0 = ambient light channel D is not in use
The bits EN_CH_A/EN_CH_B can be used to switch off channels that are not needed, and thus reducing the
current consumption. When going into Sleep or Standby the setting of these bits is ignored, all channels will
be switched off independently of EN_CH_A/EN_CH_B.
The bits EN_TEMP/EN_CH_C/EN_CH_D/EN_CH_E are used to indicate which channels are in use and which
channels are not in use.
In case all EN_CH_C/D/E bits are set to zero, but an ambient measurement is requested, then the Command
Invalid status flag will be set high. The measurement itself will not be executed.
