Internal Flash Memory Control Registers
6-88
ADSP-BF50x Blackfin Processor Hardware Reference
• The
TESTSET
assembly instruction of the Blackfin processor cannot
be used with a variable that resides in the internal flash memory.
• DMA writes to internal flash memory shall be avoided.
• While the internal flash memory is supported by the Blackfin pro-
cessor cache, no writes from cache to flash are supported.
Therefore, cache may only be used to support code and/or read-
only data in flash. For the same reason, the
FLUSH
and
FLUSHINV
data cache flush instructions cannot be used when the flash mem-
ory is the destination of the data in cache.
Internal Flash Memory Control Registers
In addition to the EBIU registers (see
“EBIU Registers” on page 5-9
), the
internal flash memory usage is controlled by the following registers:
•
“Internal Flash Memory Control (FLASH_CONTROL) Register”
•
“Internal Flash Memory Control Set (FLASH_CONTROL_SET)
Register” on page 6-91
•
“Internal Flash Memory Control Clear
(FLASH_CONTROL_CLEAR) Register” on page 6-91
