7.34. Burst Read with Wrap (0CH)
http://www.elm-tech.com
The “Burst Read with Wrap (0CH)” command provides an alternative way to perform the read operation with
“Wrap Around” in QPI mode. This command is similar to the “Fast Read (0BH)” command in QPI mode, except
the addressing of the read operation will “Wrap Around” to the beginning boundary of the “Wrap Around” once
the ending boundary is reached. The “Wrap Length” and the number of dummy clocks can be configured by the
“Set Read Parameters (C0H)” command.
