VBAT operation

The VBAT pin allows to power the device VBAT domain from an external battery, an external

supercapacitor, or from VDD when no external battery and an external supercapacitor are

present.

The VBAT operation is activated when VDD is not present.

The VBAT pin supplies the RTC, the backup registers and the backup SRAM.

Note:

When the microcontroller is supplied from VBAT, external interrupts and RTC alarm/events

do not exit it from VBAT operation.

When PDR_ON pin is connected to VSS (Internal Reset OFF), the VBAT functionality is no

more available and VBAT pin should be connected to VDD.

Timers and watchdogs

The devices include two advanced-control timers, eight general-purpose timers, two basic

timers and two watchdog timers.

All timer counters can be frozen in debug mode.

Table 6 compares the features of the advanced-control, general-purpose and basic timers.
