Description

RCC reset status register

Fields

RMVF

remove reset flag Set and reset by software to reset the value of the reset flags.

0 (B_0x0): reset of the reset flags not activated (default after power-on reset)

1 (B_0x1): resets the value of the reset flags

CDRSTF

CPU domain power-switch reset flag Reset by software by writing the RMVF bit. Set by hardware when a the CPU domain exits from DStop or after of power-on reset. Set also when the CPU domain exists DStop2 but only when a pad reset has occurred during DStop2 (PINRST bit also set by hardware)

0 (B_0x0): no CPU domain power-switch reset occurred

1 (B_0x1): CPU domain power-switch (ePOD2) reset occurred (default after power-on reset)

BORRSTF

BOR reset flag Reset by software by writing the RMVF bit. Set by hardware when a BOR reset occurs (pwr_bor_rst).

0 (B_0x0): no BOR reset occurred

1 (B_0x1): BOR reset occurred (default after power-on reset)

PINRSTF

pin reset flag (NRST) Reset by software by writing the RMVF bit. Set by hardware when a reset from pin occurs.

0 (B_0x0): no reset from pin occurred

1 (B_0x1): reset from pin occurred (default after power-on reset)

PORRSTF

POR/PDR reset flag Reset by software by writing the RMVF bit. Set by hardware when a POR/PDR reset occurs.

0 (B_0x0): no POR/PDR reset occurred

1 (B_0x1): POR/PDR reset occurred (default after power-on reset)

SFTRSTF

system reset from CPU reset flag Reset by software by writing the RMVF bit. Set by hardware when the system reset is due to CPU.The CPU can generate a system reset by writing SYSRESETREQ bit of AIRCR register of the core M7.

0 (B_0x0): no CPU software reset occurred (default after power-on reset)

1 (B_0x1): a system reset has been generated by the CPU

IWDGRSTF

independent watchdog reset flag Reset by software by writing the RMVF bit. Set by hardware when an independent watchdog reset occurs.

0 (B_0x0): no independent watchdog reset occurred (default after power-on reset)

1 (B_0x1): independent watchdog reset occurred

WWDGRSTF

window watchdog reset flag Reset by software by writing the RMVF bit. Set by hardware when a window watchdog reset occurs.

0 (B_0x0): no window watchdog reset occurred from WWDG (default after power-on reset)

1 (B_0x1): window watchdog reset occurred from WWDG

LPWRRSTF

reset due to illegal CD DStop or CD DStop2 or CPU CStop flag Reset by software by writing the RMVF bit. Set by hardware when the CPU domain goes erroneously in DStop or DStop2, or when the CPU goes erroneously in CStop.

0 (B_0x0): no illegal reset occurred (default after power-on reset)

1 (B_0x1): illegal CD DStop or CD DStop2 or CPU CStop reset occurred
