registers MAMR0 to MAMR3 are used to set the size of the CS0 to CS3 areas by
specifying a mask for each bit of the start address set in memory start address
registers MAMR0 to MAMR3. The compare operation used to determine if an address
is in the CS0 to CS3 areas is only performed for bus address bits corresponding to bits
set to 0 in these registers. Also, the address bits that can be masked by MAMR0 to
MAMR3 differ between CS0 to CS3 areas. Accordingly, the size that can be each area is
different.
Range of possible settings for CS0 area size: 256 bytes to 2 Mbytes
Range of possible settings for CS1 area size: 256 bytes to 4 Mbytes.
Range of possible settings for CS2 and CS3 area sizes: 32 Kbytes to 8 Mbytes.
