+# these tests determine if the opcodes for each instruction, in each
+# addressing mode, are correct.
+#
+# The following list is used to construct the tests. The key is the
+# mneumonic and the value is a list of address mode characters as follows
+#
+# R: register/inherent
+# I: immediate
+# E: extended
+# D: direct
+# i: indexed
+# r: register to register (TFR, etc.)
+# p: psh/pul
+# each letter is followed by an = and the 2 or 4 digit opcode in hex
+# each entry is separated by a comma
