AHB Lite Multiple burst without idle transfer

Hi All,

               Consider the following burst transfers.

1. INCR4 (WR) IDLE INCR4(RD)

2. INCR4 (WR) INCR4(RD)

3. INCR4 (WR - WR1 ,WR2, IDLE, WR3 ,WR4 )   INCR4(RD)

             All the above transactions are valid transfer or not .

Can we trigger multiple burst without giving idle transfer ?

Can we trigger IDLE transfer within the burst .

Thanks & Regards
