V1.0, 2006-02
Note: The RMAP bit must be cleared/set by ANL or ORL instructions. The rest bits of
SYSCON0 should not be modified.
As long as bit RMAP is set, the mapped SFR area can be accessed. This bit is not
cleared automatically by hardware. Thus, before standard/mapped registers are
accessed, bit RMAP must be cleared/set, respectively, by software.
