7.2.5 Configuration registers
Configuration registers grant you read or write access to the parameters of the IP
configuration. The configuration registers have 2 register areas that may differ in
content.
Register numbers
The basic register numbers of both ranges are dependent on the device. The reg-
ister number is calculated by adding the number of the module register (MR) to
the number of the basic register.

Register areas
■
Registers R 101100 ... R 101165 contain the data which the controller has de-
termined from the contents of the configuration file during the boot phase. The
user has read-only access to this data.
■
Registers R 101200 ... R 101265 contain the data which are actually used to
initialize the IP interface. The user has read and write access to this data.
The data of the two register areas may differ for the following reasons:
■
Parameters of the IP interface can be changed at runtime. This affects the
value of the registers R 101200 ... R 101202.
■
The position of the DIP switch affects the actual IP address and thus the value
of R 101200.
