The following table gives a description of STA027 register list.
The STA027 device includes 256 I
described. The undocumented registers are reserved or unused. These registers must never be
accessed (in Read or in Write mode). The Read-Only registers must never be written
We can split the data flux in different time periods (see following diagram) meanwhile host registers can
be read or written :

DWT : During Whole Time (at any time during process).
DEC : During External Config (period between RUN=2 and RUN=1).
DBO : During Boot (period between RUN=0 and RUN=2).
ABO : After BOot (period after RUN=1).
AEC : After External Config (period after RUN=2).
