25.5.1
If a command is active (CCIF = 0) when the MCU enters the wait mode, the active command and any
buffered command will be completed.
The EEPROM module can recover the MCU from wait mode if the CBEIF and CCIF interrupts are enabled
(see
25.5.2
If a command is active (CCIF = 0) when the MCU enters the stop mode, the operation will be aborted and,
if the operation is program, sector erase, mass erase, or sector modify, the EEPROM array data being
programmed or erased may be corrupted and the CCIF and ACCERR flags will be set. If active, the high
voltage circuitry to the EEPROM memory will immediately be switched off when entering stop mode.
Upon exit from stop mode, the CBEIF flag is set and any buffered command will not be launched. The
ACCERR flag must be cleared before starting a command write sequence (see
“Command Write
25.5.3
In background debug mode (BDM), the EPROT register is writable. If the MCU is unsecured, then all
EEPROM commands listed in
chip mode, the only command available to execute is mass erase.
25.6
The EEPROM module does not provide any security information to the MCU. After each reset, the
security state of the MCU is a function of information provided by the Flash module (see the specific FTX
Block Guide).
