20.4.2.13 Set Field Margin Level Command
The Set Field Margin Level command, valid in special modes only, causes the Memory Controller to set
the margin level specified for future read operations of a specific P-Flash or D-Flash block.
Upon clearing CCIF to launch the Set Field Margin Level command, the Memory Controller will set the
field margin level for the targeted block and then set the CCIF flag. Valid margin level settings for the Set
Field Margin Level command are defined in
