When IR 00001 turns ON, data held at port 2 will
be written to the command data area.
IR 00003 turned ON for one cycle (as a differentiated

00000 00001
00000 00001
IR 00002 turned ON for one cycle (as a differentiated

dress FE Hex
DM 0400: Command data storage words
0008 Hex: Master's unit number 00, 8 command data

If the Equals Flag is OFF (error in writing to the Mas-
