15.3 FLASH REV “S” and ALL ROM DEVICES

15.3.1 External clock source with PLL

External clock source is not supported with the

PLL enabled.

15.3.2 LVD Startup behaviour

When the LVD is enabled, the MCU reaches its

authorized operating voltage from a reset state.

However, in some devices, the reset state is re-

leased when VDD is approximately between 0.8V

and 1.5V. As a consequence, the I/Os may toggle

when VDD is within this window.

This may be an issue especially for applications

where the MCU drives power components.

Because Flash write access is impossible within

this window, the Flash memory contents will not be

corrupted.
