STA016T

Description :

This register select the decoding data flux according

the mode written in following table.

RUN :

Address : 0x56 (86)

Type : RW - DEC

Software Reset : 0

Description :

– When a software reset occurs, register RUN

is reset (value 0) by the dsp (see I).

– When boot routines are finished, the dsp

write inside RUN register the value 2 : this is

the start of the external configuration period

(start of DEC : see I).

– When the external device wants to end the

external configuration period, it must write the

value 1 inside the register RUN: this is the run

command that starts the decoding process

(see I).

CRC_IGNORE :

Address : 0x52 (82)

Type : RW - ABO

Software Reset : 0

Description :

For decoders having CRC abilities (see each decod-

er configuration), if set to 0 enable the check of CRC,

if set to 1 disable the check of the CRC.

MUTE :

Address : 0x53 (83)

Type : RW - ABO

Software Reset : 0

Description :

For decoders having MUTE abilities (see each de-

coder configuration), if set to 0 disable the mute of the

decoder, if set to 1 enable the mute of the decoder.

Note that during a MUTE the input stream keeps on

entering.

SKIP :

Address : 0x57 (87)

Type : RW - ABO

Software Reset : 0

Description :

For data flux using USSB Input, if SKIP == n>2, de-

coder skip (n-1) out of n frames. Note that maximum

value for n is 8, and if n==0 or n==1, no frames is

skipped.

PAUSE :

Address : 0x58 (88)

Type : RW - ABO
