OpCode Command Description
Designers have access to a total of 14 OpCodes.
These OpCodes are listed in Table 2.
The name of the OpCode appears in the left hand
column. The following two columns represent the
actual binary information contained in the 20 bit
data stream. Some commands have limits on which
command can follow them. These limits are shown
