您好：
我在測試語組的時後，將程式寫在test.s時 BSET CORCON, #SATA ; Enable Saturation on Acc A BCLR CORCON, #SATA ; Disable Saturation on Acc A 這兩行設定都沒有問題 但將程式嵌入在test.c時，卻會發生錯誤 __asm__("BSET CORCON, #SATA ;"); __asm__("BCLR CORCON, #SATA ;"); 以下是錯誤訊息： C:\DOCUME~1\DOUBLE~1\LOCALS~1\Temp/ccQ6ee00.s: Assembler messages: C:\DOCUME~1\DOUBLE~1\LOCALS~1\Temp/ccQ6ee00.s:5985: Error: Invalid operands specified ('bset CORCON,#SATA'). C:\DOCUME~1\DOUBLE~1\LOCALS~1\Temp/ccQ6ee00.s:5985: Check operand #2. Operand must be between 0 and 15, inclusive. C:\DOCUME~1\DOUBLE~1\LOCALS~1\Temp/ccQ6ee00.s:5999: Error: Invalid operands specified ('bclr CORCON,#SATA'). C:\DOCUME~1\DOUBLE~1\LOCALS~1\Temp/ccQ6ee00.s:5999: Check operand #2. Operand must be between 0 and 15, inclusive. 因為我查SATA是第7bit，所以不知道我改為這樣寫對不對？ __asm__(" BSET CORCON, #7 "); __asm__(" BCLR CORCON, #7 "); 題外話，因為我有試過把這2行註解掉，對我的MAC測試程式沒有差異，不知道SATA這個暫存器的功用為何？ 謝謝！
