7.31. Set Read Parameters (C0H)
http://www.elm-tech.com
In QPI mode the “Set Read Parameters (C0H)” command can be used to configure the number of dummy
clocks for “Fast Read (0BH)”, “Quad I/O Fast Read (EBH)” and “Burst Read with Wrap (0CH)” command, and
to configure the number of bytes of “Wrap Length” for the “Burst Read with Wrap (0CH)” command. The “Wrap
Length” is set by W5-6 bit in the “Set Burst with Wrap (77H)” command. This setting will remain unchanged
when the device is switched from Standard SPI mode to QPI mode.
