Data Enable Registers
Note:
All data records
have the same enable
states. The user does not
have to read the enable
registers for every record.
The 31xxx register series is used to determine which data items in
30xxx are enabled. Enabled items contain recorded data. Data
retrieved from disabled items return garbage. Data items are disabled
for particle and analog channels not supported by the device or when
the device software is configured not to record data for those items.
The Enable Registers (31xxx series) run in parallel with the Data
Registers (30xxx series). For example, Data Register 30010’s Enable
Register is 31010. Data Register 30016’s Enable Register is 31016.
The 31xxx register states are:
00000000h = Disabled
FFFFFFFFh = Enabled
Data Type Registers
Note:
All data records
have the same data types
assigned to them. The user
does not have to read the
data type registers for
every record.
The 32xxx register series is used to identify the type of data in the
30xxx series. The Data Type registers run in parallel with the Data
Registers. For example, Data Register 30041’s Data Type register is
32041.
Data Types are assigned 4 ASCII characters across 2 registers. If a
Data Type string contains less than 4 characters, then the rest of the
string is padded with NULL characters. Note that a Data Type using all
four characters will not end with a NULL character. Table A-15
displays the Data Type Register Strings and their meanings.
