8.2.1
Cache Control Register 1 (CCR1)
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 a cache-disabled space, and a
cache-enabled space should be accessed after reading the contents of CCR1.
CCR1 is initialized to H'00000000 by a power-on reset but not initialized by a manual reset or in
software standby mode.
