Description

RCC control/status register 2

Fields

LSION

LSI oscillator enable Set and cleared by software to enable/disable the LSI oscillator:

0 (B_0x0): Disable

1 (B_0x1): Enable

LSIRDY

LSI oscillator ready Set and cleared by hardware to indicate when the LSI oscillator is ready (stable): After the LSION bit is cleared, LSIRDY goes low after 3 LSI oscillator clock cycles. This bit can be set even if LSION = 0 if the LSI is requested by the Clock Security System on LSE, by the Independent Watchdog or by the RTC.

0 (B_0x0): Not ready

1 (B_0x1): Ready

RMVF

Remove reset flags Set by software to clear the reset flags.

0 (B_0x0): No effect

1 (B_0x1): Clear reset flags

OBLRSTF

Option byte loader reset flag Set by hardware when a reset from the Option byte loading occurs. Cleared by setting the RMVF bit.

0 (B_0x0): No reset from Option byte loading occurred

1 (B_0x1): Reset from Option byte loading occurred

PINRSTF

Pin reset flag Set by hardware when a reset from the NRST pin occurs. Cleared by setting the RMVF bit.

0 (B_0x0): No reset from NRST pin occurred

1 (B_0x1): Reset from NRST pin occurred

PWRRSTF

BOR or POR/PDR flag Set by hardware when a BOR or POR/PDR occurs. Cleared by setting the RMVF bit.

0 (B_0x0): No BOR or POR occurred

1 (B_0x1): BOR or POR occurred

SFTRSTF

Software reset flag Set by hardware when a software reset occurs. Cleared by setting the RMVF bit.

0 (B_0x0): No software reset occurred

1 (B_0x1): Software reset occurred

IWDGRSTF

Independent window watchdog reset flag Set by hardware when an independent watchdog reset domain occurs. Cleared by setting the RMVF bit.

0 (B_0x0): No independent watchdog reset occurred

1 (B_0x1): Independent watchdog reset occurred

WWDGRSTF

Window watchdog reset flag Set by hardware when a window watchdog reset occurs. Cleared by setting the RMVF bit.

0 (B_0x0): No window watchdog reset occurred

1 (B_0x1): Window watchdog reset occurred

LPWRRSTF

Low-power reset flag Set by hardware when a reset occurs due to illegal Stop, or Standby, or Shutdown mode entry. Cleared by setting the RMVF bit. This operates only if nRST_STOP, or nRST_STDBY or nRST_SHDW option bits are cleared.

0 (B_0x0): No illegal mode reset occurred

1 (B_0x1): Illegal mode reset occurred
