ABSTRACT:
A data communication method includes evaluating a data frame to determine vulnerability of the data carried by the data frame, setting a flag to a first state to indicate vulnerable data which should be checked for errors by a destination system, and setting the flag to a second state to indicate invulnerable data which should not be checked for errors by the destination system. In another aspect of the invention, a data communication method includes evaluating a data bus to determine the waveform of data transmitted on the data bus, and determining a scope of error detection and correction for the destination address to carry out based on the waveform quality.
