Section 4 Caches
• CB: Copy-back bit
• WT: Write-through bit
• OCE: OC enable bit
Notes: 1. No compatibility for RAM mode in OC index mode and address assignment in RAM
(2) Queue Address Control Register 0 (QACR0): Longword access to QACR0 can be
performed from H'FF00 0038 in the P4 area and H'1F00 0038 in area 7. QACR0 specifies the area
onto which store queue 0 (SQ0) is mapped when the MMU is off.
(3) Queue Address Control Register 1 (QACR1): Longword access to QACR1 can be
performed from H'FF00 003C in the P4 area and H'1F00 003C in area 7. QACR1 specifies the
area onto which store queue 1 (SQ1) is mapped when the MMU is off.
4.3
4.3.1
The operand cache of the SH7750 or SH7750S is of the direct-mapping type and consists of 512
cache lines, each composed of a 19-bit tag, V bit, U bit, and 32-byte data. The SH7750R's operand
cache is 2-way set-associative. Each way consists of 512 cache lines.
Figure 4.2 shows the configuration of the operand cache for the SH7750 and SH7750S.

REJ09B0366-0700
Indicates the P1 area cache write mode.
0: Write-through mode
1: Copy-back mode
Indicates the P0, U0, and P3 area cache write mode. When address translation is performed,
the value of the WT bit in the page management information has priority.
0: Copy-back mode
1: Write-through mode
Indicates whether or not the OC is to be used. When address translation is performed, the OC
cannot be used unless the C bit in the page management information is also 1.
0: OC not used
1: OC used
2. When the ORA bit is 1 in the SH7750R, the OIX bit should be cleared to 0.
3. When the OIX bit in the SH7750R is 1, the ORA bit should be cleared to 0.
