ERROR HANDLING

The ERROR indication notifies the SC that an error has occurred in previously submitted EXEC PROC commands with

ID msg_id. Table 54 shows all possible error codes. After the detection of an error, the current command is aborted and

the DSP continues execution of the next command in the input queue.

Table 54 Error codes

Note

1. These error codes do not notify a real error; they indicate the occurrence of a special event.
