Hi Venketesh,
Below factors controls the burst:
Burst_length: AxLEN[7:0]
Burst_size : AxSIZE[3:0]
Burst_type : AxBURST[1:0]
While length can be 1 to 256 for an INCR, size could be 1 to 16, the max burst can be 256*16 giving a size of 4KB.
I hope this helps.
Regards,
Nishant

Hi Nishant,
I understand what you are saying, But what is the reason for that.
Axsize is also 3bit not 4 bit.
Thanks
