ERROR WORD
The 16-bit error word indicates errors that occurred during execution of the last command. If an error
is detected, the command is not processed; the EV_ERROR bit in the status word is set to 1, and the
MWRQST signal is activated (set to 0).
The GEW command reads the error word. The error word is cleared during reset and after execution
of the GEW command.
If errors ERR_COMMAND or ERR_PARAM occur during the execution of a command that has a return
value, the return value is undefined. The microcontroller must still read the return value, to ensure prop-
er synchronization.
The bits of the error word are used as follows:
ERR_OPCODE
Illegal opcode. The VoiceDSP processor does not recognize the opcode.
ERR_COMMAND
Illegal command sequence. The command is not legal in the current state.
ERR_PARAM
Illegal parameter. The value of the parameter is out of range, or is not appropriate for the command.
ERR_COMM
Microcontroller MICROWIRE communication error.
