Does a master always have to perform the write portion of an exclusive access?

Applies to: AXI


No. It is acceptable for a master to not perform the write portion of an exclusive access. However, it is important to note that the opposite does not apply. A master must not perform an exclusive write without first performing a matching exclusive read.
