Conguration 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.
