Hello all

Please see chapter 5.4.5 in the UM V2.0:

In order to differentiate between data accesses from safe and regular tasks a new safe task identification bit is
introduced into the PSW register (PSW.S).

With this bit you can decide which MASTER TAG ID is used on internal bus for a read/write access (see table 85 in UM).
