AHB SLAVE DOUBTS

Hi,

AHB sklve give 4 kind of responses -

1. OKAY --> when everything going smoothly
2. ERROR --> READ or WRITE failed may be because the location targeted is not available in slave or somthing else error in slave.

3. RETRY --> slave can not complete transactin how but can compliete after some time so master can try after some time

4. SPLIT --> Slave needs long time to compete transaction so arbitor can give bus to other masters, slave will indicate with hsplit when it is ready for transaction.



Regading second question, the slave has to take care of wrap.

Regards,
Ramchandra
