13.4.5.12 Set User Margin Level Command
The Set User Margin Level command causes the Memory Controller to set the margin level for future read
operations of the P-Flash or D-Flash block.
Upon clearing CCIF to launch the Set User Margin Level command, the Memory Controller will set the
user margin level for the targeted block and then set the CCIF flag.
Valid margin level settings for the Set User Margin Level command are defined in
464
Register
FSTAT
When the D-Flash block is targeted, the D-Flash user margin levels are
applied only to the D-Flash reads. However, when the P-Flash block is
targeted, the P-Flash user margin levels are applied to both P-Flash and D-
Flash reads. It is not possible to apply user margin levels to the P-Flash
block only.
