4 Host register

The following table gives a description of STA027 register list.

The STA027 device includes 256 I2C registers. In this document, only the user-oriented registers are

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).

● EDF : Every Decoded Frame (each time a frame has been decoded).

● EDB : Every Decoded Block (each time a block has been decoded).
