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.
These registers run in parallel with the data registers (30xxx series).
For example, data register 30010’s enable register would be 43010.
Data register 30016’s enable register would be 43016.
Note:
Alarm Enable
currently only works for
Particle Channels.
The user can enable multiple particle channels for alarming at the same
time.
Particle data registers for the Enable setting start at 43009 for the high
word and 43010 for the low word for particle channel 1.
