pc13번 언급이 있어서 확인해보니 RTC_OUT / RTC_TAMPER로 설정이 가능하다.
Tamper를 활성화 하면 RTC_OUT 에서 RTC Output on the Tamper pin이 사용 불가능해진다.
Tamper는 인터럽트가 있는걸 봐서는.. 일종의 input 으로 설정되나보다.
rtc_Tamper를 rtc out으로 쓰지 않으면, 기본으로 tamper는 disble 되는 듯

*** Tamper configuration *** ============================ [..] (+) Enable the RTC Tamper and configure the Tamper Level using the HAL_RTCEx_SetTamper() function. You can configure RTC Tamper with interrupt mode using HAL_RTCEx_SetTamper_IT() function. (+) The TAMPER1 alternate function can be mapped to PC13

1.9 Backup registers RTC_BKPxR, where x=0 to n backup registers (80 bytes), are reset when a tamper detection event occurs. These registers are powered-on by VBAT when VDD is switched off, so that they are not reset by a system reset, and their contents remain valid when the device operates in low-power mode. Note: The number “n” of backup registers depends on the product. Please refer to Table 15: Advanced RTC features.
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

For ELF targets, the .type directive is used like this:
.type name , type description This sets the type of symbol name to be either a function symbol or an object symbol. There are five different syntaxes supported for the type description field, in order to provide compatibility with various other assemblers.
Because some of the characters used in these syntaxes (such as ‘@’ and ‘#’) are comment characters for some architectures, some of the syntaxes below do not work on all architectures. The first variant will be accepted by the GNU assembler on all architectures so that variant should be used for maximum portability, if you do not need to assemble your code with other assemblers.
STT_FUNC function Mark the symbol as being a function name.
STT_GNU_IFUNC gnu_indirect_function Mark the symbol as an indirect function when evaluated during reloc processing. (This is only supported on assemblers targeting GNU systems).
STT_OBJECT object Mark the symbol as being a data object.
그래서 reset 누르고 재기동 하면 ACM이 살아는 있지만 정상적으로 작동을 하지 않는건가?
If you reset the bluepill you need to pull down the D+ line for several milliseconds to let know the host that it has to start the enumeration process.
느린(?) eclipse 사용을 감수하는 이유가 cubeMX 설치없이 cubeIDE 에서 다 할 수 있어서 였는데
그 장점을 포기한 분리라.. 왜 이런 쓰레기 결정이 통과된거지?
We are pleased to announce that STM32CubeIDE 2.0.0 release is available. STM32CubeIDE is now independent from STM32CubeMX. With this release, device configuration, previously handled within STM32CubeIDE via STM32CubeMX, is now exclusively available through the stand-alone STM32CubeMX tool. Users will configure microcontroller peripherals and generate initialization code separately in STM32CubeMX, then import the generated projects into STM32CubeIDE for coding and debugging. STM32CubeIDE, is now a stand-alone tool, offers the possibility to create empty project through its own MCU/Board selectors now present inside. What does this change mean for developers?
Separate download and installation: STM32CubeMX is no more integrated in STM32CubeIDE, requiring separate download alongside STM32CubeIDE 2.0.0 for configuration and code generation.
Tool update flexibility: Developers can update and freeze STM32CubeMX and STM32CubeIDE independently, with multiple versions of each installed side-by-side.
Memory footprint and performance: Removing STM32CubeMX integration reduces installation size (~3.7GB to 2.9GB) and lowers CPU/RAM usage, improving stability especially on Linux and Mac.
Other relevant updates in STM32CubeIDE 2.0.0
Microcontroller, microprocessor, and board lists aligned with STM32CubeMX v6.16.0:
Added the support for new microcontrollers in the STM32N6 series
Added the support for new microcontrollers in the STM32H5 series
Added the support for new microcontrollers in the STM32WBA series
Added the support for new microcontrollers in the STM32WL3x product line
Added the support for new boards: NUCLEO-WL3RKB1 and NUCLEO-WL3RKB2
User authentication removed
ST-MCU-FINDER-PC removed
Support for ST-ARM-CLANG, STMicroelectronics LLVM-based toolchain for Arm®, through site update mechanism
Support for GCC 14 toolchain through site update mechanism
Support for semihosting feature through debug via ST-LINK GDB server
Or update your current installation of STM32CubeIDE using: Help > Check for updates (The in-tool update does not allow updating the drivers and STLINK server tool. Full installation is required for this to be done).
