0xFFFF_FFFFH
0x0000_0000H
Address
•
In the base address (BA0), specify "0xC000" that corresponds to higher 16 bits of a start
address, while in the mask address (MA0), specify whether a comparison of addresses in the
space A29 through A14 is to be made or not. Set bits 15 to 2 of the mask address (MA0) to
"0" in order for a comparison of A31 and A30 to be made definitely and to ensure a comparison
of A29 through A16. A comparison of A31 and A30 is always executed.
This setting allows A31 through A16 to be compared with the value specified as a start address
and A15 through A0 are masked. Therefore, a space of 64 KB from 0xC000_0000 to
0xC000_FFFF is designated as a CS0 space and the
match with an address on the bus.
To specify a space of 64 KB starting at 0xC000_0000 in the CS0 space, the base and
mask address registers must be programmed as shown below.
