Flash Operation in Low-Power Modes
23.4.11.14 Program Partition Command
The Program Partition command prepares the FlexNVM block for use as data flash,
EEPROM backup, or a combination of both and initializes the FlexRAM. The Program
Partition command must not be launched from flash memory, since flash memory
resources are not accessible during Program Partition command execution.

Table 23-64. Program Partition Command FCCOB Requirements
While different partitions of the FlexNVM are available, the
intention is that a single partition choice is used throughout the
entire lifetime of a given application. The FlexNVM Partition
Code choices affect the endurance and data retention
characteristics of the device.
