저전력 모드 보안 리셋은 멀까?
| 3.7.2 System reset sources Power-on reset initializes all registers while system reset reinitializes the system except for the debug, part of the RCC and power controller status registers, as well as the backup power domain. A system reset is generated in the following cases: • Power-on reset (pwr_por_rst) • Brownout reset • Low level on NRST pin (external reset) • Independent watchdog 1 (from D1 domain) • Independent watchdog 2 (from D2 domain) • Window watchdog 1 (from D1 domain) • Window watchdog 2 (from D2 domain) • Software reset • Low-power mode security reset • Exit from Standby |

stop / standby mode 오갈때 뜨는 듯?
| A low-power-mode security reset (which is generated when Stop or Standby mode is entered but is prohibited by the option byte configuration) |
