+//! This value may be returned from a call to EEPROMInit(). It indicates that
+//! no previous write operations were interrupted by a reset event and that the
+//! EEPROM peripheral is ready for use.
+//
+#define EEPROM_INIT_OK 0
+
+//
+//! This value may be returned from a call to EEPROMInit(). It indicates that
+//! a previous data or protection write operation was interrupted by a reset
+//! event. The EEPROM peripheral has recovered its state but the last write
+//! operation may have been lost. The application must check the validity of
+//! data it has written and retry any writes as required.
+//
+#define EEPROM_INIT_RETRY 1
+
+//
+//! This value may be returned from a call to EEPROMInit(). It indicates that a
+//! previous data or protection write operation was interrupted by a reset
+//! event and that the EEPROM peripheral was unable to clean up after the
+//! problem. This situation may be resolved with another reset or may be fatal
+//! depending upon the cause of the problem. For example, if the voltage to
+//! the part is unstable, retrying once the voltage has stabilized may clear
+//! the error.

+//
+//*****************************************************************************
+
+//
+//! This return code bit indicates that the EEPROM programming state machine
+//! failed to write a value due to the voltage level dropping below that
+//! required for EEPROM programming. The operation may be retried once the
+//! voltage stabilizes.
+//
+#define EEPROM_RC_INVPL 0x00000100
+
+//
+//! This return code bit indicates that an attempt was made to read from
+//! the EEPROM while a write operation was in progress.
+//
+#define EEPROM_RC_WRBUSY 0x00000020
+
+//
+//! This return code bit indicates that an attempt was made to write a
+//! value but the destination permissions disallow write operations. This
+//! may be due to the destination block being locked, access protection set
+//! to prohibit writes or an attempt to write a password when one is already
+//! written.
+//
+#define EEPROM_RC_NOPERM 0x00000010
+
+//
+//! This return code bit indicates that the EEPROM programming state machine
+//! is currently copying to or from the internal copy buffer to make room for
+//! a newly written value. It is provided as a status indicator and does not
+//! indicate an error.
+//
+#define EEPROM_RC_WKCOPY 0x00000008
+
+//
+//! This return code bit indicates that the EEPROM programming state machine
+//! is currently erasing the internal copy buffer. It is provided as a
+//! status indicator and does not indicate an error.
+//
+#define EEPROM_RC_WKERASE 0x00000004

+//! This return code bit indicates that the EEPROM programming state machine
+//! is currently working. No new write operations should be attempted until

+//
+#define EEPROM_PROT_SUPERVISOR_ONLY 0x00000008
+
+//
+//! This value may be passed to EEPROMBlockProtectSet() or returned from
+//! EEPROMBlockProtectGet(). It indicates that the block should offer
+//! read/write access when no password is set or when a password is set and
+//! the block is unlocked, and read-only access when a password is set but
+//! the block is locked.
+//
+#define EEPROM_PROT_RW_LRO_URW 0x00000000
+
+//
+//! This value may be passed to EEPROMBlockProtectSet() or returned from
+//! EEPROMBlockProtectGet(). It indicates that the block should offer neither
+//! read nor write access unless it is protected by a password and unlocked.
+//
+#define EEPROM_PROT_NA_LNA_URW 0x00000001
+
+//
+//! This value may be passed to EEPROMBlockProtectSet() or returned from
+//! EEPROMBlockProtectGet(). It indicates that the block should offer
+//! read-only access when no password is set or when a password is set and the
+//! block is unlocked. When a password is set and the block is locked, neither
