BOOL DC_Disable( void );
This function prohibits use of all data cache. The return value is the use permission/prohibit setting
for the data cache before this function is called.
When TRUE, use of the cache was permitted; when FALSE, it was prohibited.
Reading and writing the main memory in byte units will not function properly when data cache use is prohibited because the library were created on the assumption that the cache is enabled. Therefore, this could cause unforeseen problems, so do not prohibit the use of cache under normal conditions.
Operates register 1 of the system control coprocessor.
None.
