(2) Setting the start address and address space size
determines whether the A29-A14 bits of the address should be compared or masked. The A31 and A30
bits are always compared. Bits 15-10 of the MA0 field must be cleared so that the A29-A24 bits are
always compared.
compared to the value of the BA0 field. Consequently, the 64-Kbyte address range between
0xC000_0000 and 0xC000_FFFF is defined as the
The BA0 field specifies the upper 16 bits of the starting address, or 0xC000. The MA0 field
When the BMA0 register is programmed as shown above, the A31-A16 bits of the address are
