Margin level setting.
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.
NOTE
When the EEPROM block is targeted, the EEPROM field margin levels are
applied only to the EEPROM reads. However, when the P-Flash block is
targeted, the P-Flash field margin levels are applied to both P-Flash and
EEPROM reads. It is not possible to apply field margin levels to the P-Flash
block only.
Valid margin level settings for the Set Field Margin Level command are defined in Table 30-58.
