Galileo EPD Bus Commands

Source: R. C. Moore, May 30, 1979

The following lists represent the latest EPD bus commands. Commands with op-codes less than 80 are destined for the motor controller; commands with op-codes greater than 7F are destined for the data system. All bus commands are one-byte commands except for some of those listed on page 7 (op-codes D0 - D6, D9 - DE). In the case of one-byte commands, bits 17-24 of the uplink command word do not have any meaning and do not need to be sent to the data system via the bus adapter.
