4.40.4.5.13
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 the 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
Freescale Semiconductor
Register
FSTAT
User margin levels can be used to check that Flash memory contents have adequate margin
for normal level read operations. If unexpected results are encountered when checking
Flash memory contents at user margin levels, a potential loss of information has been
detected.
Set Field Margin Level Command
When the D-Flash block is targeted, the D-Flash field margin levels are applied only to the
D-Flash reads. However, when the P-Flash block is targeted, the P-Flash field margin levels
are applied to both P-Flash and D-Flash reads. It is not possible to apply field margin levels
to the P-Flash block only.
