Limitation is disabled, as many blocks are decoded as possible.
The number of predecoded blocks is limited to a defined value. The
maximum value depends on the available memory and from the setting
in the flexible memory configuration. If the existing number of block
buffers is exceeded, as many blocks as possible are predecoded.
The minimum value is 2 here. If the value 1 is entered it is
automatically switched over to 2.
