Bit 2—RAM Select (RAMS): Specifies selection or non-selection of flash memory emulation in RAM. When RAMS =
1, all flash memory block are program/erase-protected.
Bits 1 and 0—Flash Memory Area Selection (RAM1, RAM0): These bits are used together with bit 2 to select the flash
memory area to be overlapped with RAM. (see table 19-13.)
