The academic committee of the program for which you have applied for admission can decide, in view of your previous education, whether you must obtain a number of compulsory additional credits. These credits are known as supplementary training.
This specific supplementary training, for the purposes of awarding study grants and aids, is regarded as doctoral level training, but for the purposes of public prices it is regarded as consisting of master's degree ECTS credits.
When you receive the e-mail for admission you will see the supplementary training which, if appropriate, you must complete during the first two years of the doctorate.
You can find the specific requirements on the program website. Bear in mind that the allocation of this supplementary training is individualized and corresponds to the academic committee of each program.
