• In double-size cache mode (EMODE = 1 in CCR)
7.3.6
Setting the OIX bit in CCR to 1 enables OC indexing to be performed using bit [25] of the
effective address. This is called OC index mode. In normal mode, with the OIX bit in CCR cleared
to 0, OC indexing is performed using bits [13:5] of the effective address. Using index mode allows
the OC to be handled as two 8-Kbyte areas by means of effective address bit [25], providing
efficient use of the cache. This LSI cannot be used in RAM mode when OC index mode is
selected.
7.3.7
Coherency between cache and external memory should be assured by software. In this LSI, the
following four new instructions are supported for cache operations. Details of these instructions
are given in the Programming Manual.

In this mode, the 8 Kbytes comprising entries 256 to 511 of OC way 0 are designated as RAM
area 1 and the 8-Kbytes comprising entries 256 to 511 of OC way 1 are designated as RAM
area 2.
H'7C00 0000 to H'7C00 1FFF (8 Kbytes): Corresponds to RAM area 1
H'7C00 2000 to H'7C00 3FFF (8 Kbytes): Corresponds to RAM area 2
H'7C00 4000 to H'7C00 5FFF (8 Kbytes): Corresponds to RAM area 1
H'7C00 6000 to H'7C00 7FFF (8 Kbytes): Corresponds to RAM area 2
In the same pattern, shadows of the RAM area are created in 16-Kbyte blocks until H'7FFF
FFFF is reached.
