Description
5 to 4 RES1 to
RES0
Bits to set the code segment of the area to remap.
For example, when writing "0x1" to RES1-0 and "0xF" to REA15-12, then remapping them,
the area of 0xF000-0xFFFF of code segment 1 is remapped with the area of 0x0000-0x0FFF
of segment 0.
Reset RES1 bits and RES2 bit to "0" on the products that have 64Kbyte or smaller program
memory space (Memory model: SMALL).
3 to 0 REA15 to
REA12 Bits to set the higher 4 bits (bit 15 to 12) of the beginning address of the area to be remapped.
For example, when writing "0xF" to REA15-12, then remapping them, the area of
0xF000-0xFFFF is remapped with the area 0x0000-0x0FFF.
