In V2.1 mode the AS-i I/O data are mapped in the PROFIBUS pro-
cess data as known from the Siemens and AS-i/InterBus masters.
That means the lower nibble describes the data of the AS-i slave
with the higher slave address. The EC flags resp. HI-flags are addi-
tionaly mapped at the nibble of AS-i slave 0.
