When programming the CRAM_RBAx registers, the CALRAM can be put in overlay mode by setting the
OVL bit in the CALRAM overlay configuration register (CRAMOVL) as described in section
Section 22.5.3, “CALRAM Overlay Configuration Register
Figure 22-5
in the Flash as specified by CRAM_RBA0, CRAM_RBA4, and CRAM_RBA5. Overlay region 1 is
partially mapped to a region in Flash as specified by the CRAM_RBA1. If the region size of 256 bytes is
selected for overlay region 1, for example, then the enabled portion of overlay region 1 will occupy address
0x3F F200 to 0x3F F2FF. The rest of overlay region 1 from 0x3F F300 to 0x3F F3FF is available for
normal (non-overlay) array access. Overlay regions 2, 3, 6, and 7 are disabled for overlay and hence can
be used, in their entirety, for normal (non-overlay) array accesses.
