[AXI protocol] Is a master allowed to disable byte lanes in a non-narrow WRAP burst?

Hello,

A couple of further details on the question.

Let's assume that I have a 64-bit data bus and a 32-bit address bus.

A master issues a WRAP burst with AWADDR[31:0] = 32'd8 and AWSIZE[2:0] = 3'b110. That is, the start address is 8 and the beat size is 64 bits (thus the burst is non-narrow).

I am trying to understand if there are any restrictions on the value of WSTRB[7:0]: can the master disable byte lanes in this burst?

Thanks in advance for your help.

Regards,

Zax
