When the CPU is delivered it has been reset.
After a STOP → RUN transition the CPU switches to RUN without
program.
After NETZ_EIN (power on), the DP master tries to get parameters from
the CPU.
For the master doesn't get valid parameters from the CPU, it starts with
default parameters (Addr.:1, 1.5MBit) from its ROM and shows this via the
"IF"-LED.
