EPU Commands

There are two command types:
•
Two Part Commands
• Three Part Commands
Any number of two-part and three part commands may be issued in any combination before
the command control level is exited. If the command control level is exited before a two- or
three-part command is completed, the command is aborted and becomes a NOP.
