Section 8 Cache
8.2
The cache has the following registers.
Table 8.2
8.2.1
The instruction cache is enabled or disabled using the ICE bit. The ICF bit controls disabling of all
instruction cache entries. The operand cache is enabled or disabled using the OCE bit. The OCF
bit controls disabling of all operand cache entries. The WT bit selects either write-through mode or
write-back mode for operand cache.
Programs that change the contents of CCR1 should be placed in an address space that is not
cached, and an address space that is cached should be accessed after reading the contents of
CCR1.
CCR1 is initialized to H'00000000 by a power-on reset and in deep standby but not initialized by a
manual reset or in software standby mode.
