Configuration Registers
The DTS Series module contains several registers that control its
configuration and operation. The register settings are stored in two types
of memory inside the module. Volatile memory is quick to access, but it is
lost when power is removed from the module. Non-volatile memory takes
longer to access, but is retained when power is removed.
All of the configuration settings have registers in both types of memory.
The settings are read from non-volatile registers on power up and saved
in volatile registers since it is faster to read and write the volatile memory
locations. There are commands to read and write both locations.
During normal operation, the volatile registers are used to control the
module. Figure 13 shows all of the configuration registers. Figure 12 shows
the default values for the non-volatile registers. These are what the module
uses when it powers up. Changing these values changes the module’s
default setting.
