Disable the cache before entering the standby mode for power-down operation. After returning

from standby, initialize the cache before use.

Changing the contents of CCR also changes cache operation. The chip makes full use of pipeline

operations, so it is difficult to synchronize access. For this reason, change the contents of the cache

control register simultaneously when disabling the cache or after the cache is disabled. After

changing the CCR contents, perform a CCR read.
