HOST REGISTERS

The following table gives a description of STA016A register list.

The STA016A device includes 256 I2C registers. In this document, only the user-oriented registers are de-

scribed. 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).
