How was your experience today?

BUSY transfer and WAIT state both are using the same time ,How to perform the AHB?

rajaraman r

Hi sir,

       T1=NON-SEQ

       T2=BUSY

       T3=SEQ

       T4=SEQ

      T5= SEQ

         This is for WRITE operation:

         i am  using a BUSY state for T2. Then my WAIT state for till T3.  I have read from the forum if WAIT state u are using a BUSY transfer, you can change next clock on the  valid transfer.

         If i change the HTRANS to the valid transfer my T1 data will  be maintained for till T3 clock. Then what about the BUSY transfer.

       This same as applicable for READ operation.And this is only for WAIT STATE.

 Regards

    Thank You Collin for your answer.

    I still have a doubt that at T2 i am sending busy from master to slave in my HTARNS then how come my slave can send me HREADY=LOW at same instance of time i.e T2.

    Slave might  get this acknowledgement at next rising edge of clock which is T3,so i guess at T3 HREADY should go low,But at T2 its getting low.

    So,is there any connection between HTRANS and HREADY.

    Waiting for your response.

    Thanks in advance.
