-     c - a 5-bit control register index or break opcode
+     c - a 5-bit control register index
      d - a 5-bit destination register index
      s - a 5-bit left source register index

      j - a 5-bit unsigned immediate
-     k - a 6-bit unsigned immediate
-     l - an 8-bit unsigned immediate
+     b - a 5-bit break instruction constant
+     l - a 8-bit custom instruction constant
      m - a 26-bit unsigned immediate
    Literal ',', '(', and ')' characters may also appear in the args as
    delimiters.
