 * Global Miscellaneous Control Register
 * This register controls all Gemini pad/pin multiplexing

 * It is a tricky register though:
 * - For the bits named *_ENABLE, once you DISABLE something, it simply cannot
 *   be brought back online, so it means permanent disablement of the
 *   corresponding pads.
 * - For the bits named *_DISABLE, once you enable something, it cannot be
 *   DISABLED again. So you select a flash configuration once, and then
