10.2.39 Burst Read with Wrap (0Ch)
The “Burst Read with Wrap (0Ch)” instruction provides an alternative way to perform the read operation
with “Wrap Around” in QPI mode. The instruction is similar to the “Fast Read (0Bh)” instruction in QPI
mode, except the addressing of the read operation will “Wrap Around” to the beginning boundary of the
“Wrap Length” once the ending boundary is reached.
The “Wrap Length” and the number of dummy clocks can be configured by the “Set Read Parameters
(C0h)” instruction.
