ADSP-BF535 Flags
ADSP-BF535 Flags
Table A-1 lists the Blackfin processor instruction set and the affect on
flags when these instructions execute on an ADSP-BF535 processor. The
symbol definitions for the flag bits in the table are as follows.
• – indicates that the flag is NOT AFFECTED by execution of the
instruction
• * indicates that the flag is SET OR CLEARED depending on exe-
cution of the instruction
• ** indicates that the flag is CLEARED by execution of the
instruction
• U indicates that the flag state is UNDEFINED following execution
of the instruction; if the value of this bit is needed for program exe-
cution, the program needs to check the bit prior to executing the
instruction with a U in a bit field.
The flags with undefined (U) results on the ADSP-BF535 have
defined results on subsequent Blackfin processors.
Because the AC0, AC1, V, AV0, AV1, AV0S, and AV1S flags do
not exist on the ADSP-BF535, these flags do not appear in
Table A-1.
