Structure of the parameter assignment error byte
The parameter assignment error byte (PAFE) informs you about various
parameter assignment errors. When you assign parameters to the individual
blocks, you specify the address at which this information is available. The
meaning of the individual bits is explained in Fig. 8.6.
