the ADSP489 DATA 0-7 connect DATA0-7
the ADSP21489 A 0-11 connect A0-11
the ADSP21489 RD，WR connect RD，WR
MSO connect CS
In my project, the adsp-21489 connect a profibus chip,using as a asynchronous memory .
now ,the signal of cs,rd,wr,and the addr is ok,but the signal of data has some problem.when i send the oxff to the data ,all the signal of data is like this ;
*pSYSCTL |= EPDATA32;
*pEPCTL |=B0SD; // Mapping Bank 0 to non SDRAM
*pEPCTL &= ~(B1SD|B2SD|B3SD);
*pAMICTL0 = ( AMIEN | PKDIS | BW8 | WS31 | HC2 | PREDIS );
void IINCHIP_WRITE(unsigned int address,unsigned char data)
*(p_data) = data;
please give me some advice!
