All registers, except the program counter and the four general purpose register banks,
reside in the special function register area. The special function register area consists
of two portions: the standard special function register area and the mapped special
function register area. For accessing the mapped special function area, bit RMAP in
special function register SYSCON0 must be set. All other special function registers are
located in the standard special function register area which is accessed when RMAP is
cleared (“0“).

As long as bit RMAP is set, the mapped special function register area can be accessed.
This bit is not cleared automatically by hardware. Thus, when non-mapped/mapped
registers are to be accessed, the bit RMAP must be cleared/set respectively by software.
