Burst Read with Wrap (0CH)

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.
