STA450A

HOST_ERRINTEH - HOST_ERRINTEL

Address

: 0x4A - 0x49

Type

: R/W

Software Reset

: NA

Hardware Reset

: NA

Description

These registers are associated to error condition inside the STA450A.

The STA450A contains a 16 bit interrupt register associated with 16 bit enable register.

A bit set in this register will enable the generation of an external interrupt on the interrupt line. The

interrupt associated with each bit is given in the register INT description.

HOST_ERRINTH - HOST_ERRINTL

Address

: 0x4B - 0x4C

Type

: R/W

Software Reset

: NA

Hardware Reset

: NA

Description

These registers are associated to error condition inside the STA450A.

A bit set in this table indicates the corresponding event has been occurred. Whenever the corresponding

bit in the INTE table has been set an external interrupt is generated.

To clear the bit a fast command has to be issued (see command description).

Service Layer Lost

Synchronization

0x4B 0x01 Service Layer Lost synchronisation due to communication error with

CDEC

TSCC RSError

0x02 TSCC have RS errors

Bitstream Communication Failure

0x04 The format of communication is not compatible with the bitstream

input I/F. The DSP need to be restarted

Service Layer incorrect status

0x08 Service Layer have reached an incorrect status.

NoBacFromCdec

0x10 The BAC wasn’t received from the CDEC in the last frame

Rollback

0x20 Error from decryption

PicIOError

0x40 Communication error with the CAP device

Audio Decoder Not Working

0x80 Error in the audio decoder

NV Memory Unreadable

0x4C 0x01 Data corrupted in the NVM

ExtractionError_0

0x02 Some error occurs during extraction of channel in location 0, to obtain

detailed situation System Controller must raise a command. At the

time of this command is raised the DSP clear the error buffer

ExtractionError_1

0x04 Some error occurs during extraction of channel in location 1, to obtain

detailed situation System Controller must raise a command. At the

time of this command is raised the DSP clear the error buffer
