8.2.33 Burst Read with Wrap (0Ch)
The âBurst Read with Wrap (0Ch)â instruction provides an alternative way to perform the read operation
with âWrap Aroundâ in QPI mode. The instruction is similar to the âFast Read (0Bh)â instruction in QPI mode,
except the addressing of the read operation will âWrap Aroundâ to the beginning boundary of the âWrap
Lengthâ once the ending boundary is reached.
The âWrap Lengthâ and the number of dummy clocks can be configured by the âSet Read Parameters
(C0h)â instruction.
