15.4.5.13 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 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

As defined by the memory map for FTMRC64K1.

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.
CCOBIX[2:0]
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.
