WKUP_RC_OSC_12M in always oscillate mode.
The 12.5-MHz RC clock output (WKUP_RC_OSC_12M) is used by the on-chip Reset Glue logic, Power Reset Generator (PRG) circuits, WKUP_HFOSC0 Loss Circuits, Dual Clock Comparator (DCC) and Timer Modules.
An output clock of WKUP_RC_OSC_12M is further divided down to generate a 32-kHz clock (CLK_32K). This clock is used by WKUP_DMSC0 and Timer Modules.
The actual value of the derived CLK_32K will vary with PVT variations. For more information, see the device-specific Datasheet.
If an application needs accurate 32.768-kHz clock, then use the WKUP_LF_CLKIN external clock input.
