When the system clock (MCK) is lower than 2.5 MHz with 2 Wait States (WS) programmed in
the EEFC Flash Mode Register (EEFC_FMR), the Cortex fetches erroneous instructions.
Do not use 2 WS when running at a frequency lower than 2.5 MHz.
Higher than expected power consumption can be seen when reading Flash in 64-bit mode.
Use 128-bit mode instead.
When writing data into the Flash memory plane (either through the EEFC, using the IAP func-
tion, or FFPI), the data may not be correctly written (i.e the data written is not the one expected).
Set the number of Wait States (WS) to 6 (FWS=6) during the programming.
In Backup mode, the current consumption on VDDANA is around 1.0 mA instead of 0.1 μA
Four workarounds are possible:
1. Do not supply VDDANA and VDDIO in Backup mode using an external switch managed
2. Do not supply VDDANA in Backup mode using an external switch managed by the
3. Do not supply VDDANA in Backup mode using an external switch managed by any PIO

by SHDN pin.
SHDN and set all PIOs with ADC inputs (PA22, PA30, PB3-PB8, PC15-PC18, PC28-
C21) at low level (either externally or by software).
and set all PIOs with ADC inputs (PA22, PA30, PB3-PB8, PC15-PC18, PC28-C21) at
low level (either externally or by software). Since the PIO state is preserved when in
backup mode, any free PIO line can be used to switch off the external switch by driving
the PIO line at low level (PIO is input, pull-up enabled after backup reset).
