Description
RAM Select
Specifies selection or non-selection of flash memory
emulation in RAM. When RAMS = 1, the flash memory is
overlapped with part of RAM, and all flash memory block
are program/erase-protected.
Flash Memory Area Selection
When the RAMS bit is set to 1, one of the following flash
memory areas is selected to overlap the RAM area. The
areas correspond with 4-kbyte erase blocks.
000: H'000000 to H'000FFF (EB0)
001: H'001000 to H'001FFF (EB1)
010: H'002000 to H'002FFF (EB2)
011: H'003000 to H'003FFF (EB3)
100: H'004000 to H'004FFF (EB4)
