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.
NOTE
When the EEPROM block is targeted, the EEPROM user margin levels are
applied only to the EEPROM reads. However, when the P-Flash block is
targeted, the P-Flash user margin levels are applied to both P-Flash and
EEPROM reads. It is not possible to apply user margin levels to the P-Flash
block only.
Valid margin level settings for the Set User Margin Level command are defined in Table 28-55.
