+  E0C6200 is a CPU core used as the basis of many chips, it is not standalone.
+  Seiko Epson often changed prefixes of their device names. Depending on when,
+  the E0C6200 is known as SMC6200, E0C6200, S1C6200.

   TODO:
   - RLC is part of the r,q opcodes and requires that r == q, what happens otherwise?
   - documentation is conflicting on whether or not the zero flag is set on RLC/RRC
