Data and Alarm Enable Registers
The Data and Alarm Enable input registers (43xxx series) are read/
write. All enable data items are 4 bytes long and are stored across 2
registers. Byte and word ordering is big-endian. Thus, data items are
formed by placing the high bytes in front of the low bytes. For
example:
<High Bytes><Low Bytes> = <4 Byte Data Item>
The 43xxx register series is used to determine which particle data
channel is ENABLED and which are set to ALARM ENABLE. These
registers supersede the older Data Enable Registers (31xxx) which
have been obsoleted.
