Over-drive switching characteristics

When the over-drive mode switches from enabled to disabled or disabled to enabled, the

system clock is stalled during the internal voltage set-up.

The over-drive switching characteristics are given in Table 23. They are sbject to general

operating conditions for TA.

2. The reset temporization is measured from the power-on (POR reset or wakeup from VBAT) to the instant

when first instruction is read by the user application code.
