Standard Event Status Group
These registers are programmed by Common commands. The group consists of an Event and Enable
register.The Standard Event event register latches events relating to communication status. It is a
read-only register that is cleared when read. The Standard Event enable register functions similarly
to the enable registers of the Operation and Questionable status groups. Refer to
a description of each register. The following table describes the bit assignments.
