Burst termination with BUSY on AHB Lite

Lumi Yang

Hello,

I have some question when Master used "Undefined Length" and termination with BUSY, the following is my waveform :

My question is :

1) When T5-T6, Slave still on address phase?

2) When T6-T7, Slave can drive HREADYOUT=LOW to extend data phase?

    Thanks very much, i finally understand "the slave MUST provide a zero-wait OKAY response" what this mean.

    if slave still in data phase(have a NOSEQ or SEQ transfer is not completed), it can extend data phase whatever master is driving BUSY.

    If slave is completed transfer, the slave MUST provide a zero-wait OKAY response when master is driving BUSY.
