Data bus network interface module and method therefor

摘要

A data bus network interface module for enabling reception and transmission of application messages to/from at least one host processing module of an integrated digital signal processing device via a data bus network is described. The data bus network interface module being arranged to receive at least one data bus message from at least one remote network node via the data bus network, read an identifier field of the received at least one data bus message, and make data content of the received at least one data bus message available to at least one debug module if the identifier field comprises an identifier value defined for debug use.

1. A microcontroller device comprising:
a host processing module; a debug module; and a data bus network interface module for enabling reception and transmission of application messages to/from a remote network node via a data bus network, the data bus network interface module being arranged to:
receive a data bus message from the remote network node via the data bus network, read a non-data field of the data bus message, and make data content of the data bus message available to the debug module if the non-data field comprises a value defined for debug use; andreceive data from the debug module for transmission over the data bus network and, upon receipt of said data from the debug module, to generate a second data bus message containing the received data and comprising a second non-data field value defined for debug use.
