Hello! In the br1538.pdf - DSP56F80X High-Speed RS-232 Interface Example - 2. DSP56F803 SCI Transmit Code Snippet ------ SCISR EQU $0F02 ; SCI STATUS REGISTER SCIDR EQU $0F03 ; SCI DATA REGISTER SCI_XMIT: BFCLR #8000,X:SCISR,* ; WAIT UNTIL TRANSMIT BUFFER IS EMPTY MOVEP X0,X:SCIDR ; OUTPUT DATA BYTE RTS ----- BFCLR #8000,X:SCISR,* ; - error in this line X:SCISR is read only register, so BFCLR can't clear bits. Have anybody working example (ASM) for sci connection 56f80xEVM <----> PC (RS-232 Interface)? With best regards, Andrew Shelkovenko. |
