The bits within the Data Status Byte are flagged to indicate particular
conditions of the currently indexed data record.
If multiple states occur, the bits are added together. For example, a
Flow Alert and a Particle Overflow would return a value of 6 in register
30008 (bits 1 and 2 are set TRUE).
Bits 7 to 31 are currently unused.
Valid Data in Channels (30074)
Register 30074 represents the flag bits corresponding to valid data
present in the particle register range.
Alarm Flags in Channels (30076)
Register 30076 represents the flag bits corresponding to particle
channels that have exceeded the threshold [Threshold High Registers
(45xxx series)] based on alarm mode
