*** ARM Compiler ***
--------------------
[..] RAM functions are defined using the toolchain options.
Functions that are be executed in RAM should reside in a separate
source module. Using the 'Options for File' dialog you can simply change
the 'Code / Const' area of a module to a memory space in physical RAM.
Available memory areas are declared in the 'Target' tab of the
Options for Target' dialog.
*** ICCARM Compiler ***
-----------------------
[..] RAM functions are defined using a specific toolchain keyword "__ramfunc".
*** GNU Compiler ***
--------------------
[..] RAM functions are defined using a specific toolchain attribute
"__attribute__((section(".RamFunc")))".

voltage scaling (scale 1, scale 2 or scale 3)
(++) Over-drive mode: This mode allows the CPU and the core logic to operate at a
higher frequency than the normal mode for a given voltage scaling (scale 1,
scale 2 or scale 3). This mode is enabled through PWR_OverDriveCmd() function and
PWR_OverDriveSWCmd() function, to enter or exit from Over-drive mode please follow
the sequence described in Reference manual.
(+) For STM32F42xxx/43xxx Devices, in Stop mode: the main regulator or low power regulator
supplies a low power voltage to the 1.2V domain, thus preserving the content of registers
and internal SRAM. 2 operating modes are available:
(++) Normal mode: the 1.2V domain is preserved in nominal leakage mode. This mode is only
available when the main regulator or the low power regulator is used in Scale 3 or
low voltage mode.
(++) Under-drive mode: the 1.2V domain is preserved in reduced leakage mode. This mode is only
available when the main regulator or the low power regulator is in low voltage mode.
This mode is enabled through PWR_UnderDriveCmd() function.

* To retain the content of the RTC backup registers, backup SRAM,

* 1 - The RTC
* 2 - The LSE oscillator
* 3 - The backup SRAM when the low power backup regulator is enabled
* 4 - PC13 to PC15 I/Os, plus PI8 I/O (when available)

* to VDD), the following functions are available:
* 1 - PC14 and PC15 can be used as either GPIO or LSE pins
* 2 - PC13 can be used as a GPIO or as the RTC_AF1 pin

* RCC_BackupResetCmd().
* 2 - VDD or VBAT power on, if both supplies have previously been
* powered off.
*
* ===================================================================
* Backup Domain Access
* ===================================================================
* After reset, the backup domain (RTC registers, RTC backup data
* registers and backup SRAM) is protected against possible unwanted

* and WaKeUp signals.
* To output the selected RTC signal on RTC_AF1 pin, use the
* RTC_OutputConfig() function.

* The MCU can be woken up from a low power mode by an RTC alternate
* function.
* The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
* RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
* These RTC alternate functions can wake up the system from the Stop
* and Standby lowpower modes.
* The system can also wake up from low power modes without depending
* on an external interrupt (Auto-wakeup mode), by using the RTC alarm
* or the RTC wakeup events.
* The RTC provides a programmable time base for waking up from the
* Stop or Standby mode at regular intervals.

or RTC_AF2 depending on the value of the TSINSEL bit in the RTC_TAFCR
register. You can use the RTC_TimeStampPinSelection() function to select
the corresponding pin.
*** Backup Data Registers configuration ***
===========================================
[..]
(+) To write to the RTC Backup Data registers, use the RTC_WriteBackupRegister()
function.
(+) To read the RTC Backup Data registers, use the RTC_ReadBackupRegister()
function.
##### RTC and low power modes #####
===================================================================
[..] The MCU can be woken up from a low power mode by an RTC alternate
function.
[..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B),
RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
These RTC alternate functions can wake up the system from the Stop and
Standby lowpower modes.
[..] The system can also wake up from low power modes without depending
on an external interrupt (Auto-wakeup mode), by using the RTC alarm
or the RTC wakeup events.
[..] The RTC provides a programmable time base for waking up from the
Stop or Standby mode at regular intervals.
Wakeup from STOP and Standby modes is possible only when the RTC clock source
is LSE or LSI.
##### Selection of RTC_AF1 alternate functions #####
===================================================================
[..] The RTC_AF1 pin (PC13) can be used for the following purposes:
(+) AFO_ALARM output
(+) AFO_CALIB output
(+) AFI_TAMPER
(+) AFI_TIMESTAMP
[..]
