mbed_official | 76:aeb1df146756 | 23 | =============================================================================== |
mbed_official | 76:aeb1df146756 | 24 | ##### Backup Domain Operating Condition ##### |
mbed_official | 76:aeb1df146756 | 25 | =============================================================================== |
mbed_official | 76:aeb1df146756 | 26 | [..] The real-time clock (RTC) and the RTC backup registers can be powered |
mbed_official | 76:aeb1df146756 | 27 | from the VBAT voltage when the main VDD supply is powered off. |
mbed_official | 76:aeb1df146756 | 28 | To retain the content of the RTC backup registers and supply the RTC |
mbed_official | 76:aeb1df146756 | 29 | when VDD is turned off, VBAT pin can be connected to an optional |
mbed_official | 76:aeb1df146756 | 30 | standby voltage supplied by a battery or by another source. |
mbed_official | 76:aeb1df146756 | 31 | |
mbed_official | 76:aeb1df146756 | 32 | [..] To allow the RTC to operate even when the main digital supply (VDD) |
mbed_official | 76:aeb1df146756 | 33 | is turned off, the VBAT pin powers the following blocks: |
mbed_official | 76:aeb1df146756 | 34 | (#) The RTC |
mbed_official | 76:aeb1df146756 | 35 | (#) The LSE oscillator |
mbed_official | 76:aeb1df146756 | 36 | (#) PC13 to PC15 I/Os I/Os (when available) |
mbed_official | 76:aeb1df146756 | 37 | |
mbed_official | 76:aeb1df146756 | 38 | [..] When the backup domain is supplied by VDD (analog switch connected |
mbed_official | 76:aeb1df146756 | 39 | to VDD), the following functions are available: |
mbed_official | 76:aeb1df146756 | 40 | (#) PC14 and PC15 can be used as either GPIO or LSE pins |
mbed_official | 76:aeb1df146756 | 41 | (#) PC13 can be used as a GPIO or as the RTC_AF1 pin |
mbed_official | 76:aeb1df146756 | 42 | |
mbed_official | 76:aeb1df146756 | 43 | [..] When the backup domain is supplied by VBAT (analog switch connected |
mbed_official | 76:aeb1df146756 | 44 | to VBAT because VDD is not present), the following functions are available: |
mbed_official | 76:aeb1df146756 | 45 | (#) PC14 and PC15 can be used as LSE pins only |
mbed_official | 76:aeb1df146756 | 46 | (#) PC13 can be used as the RTC_AF1 pin |
mbed_official | 76:aeb1df146756 | 47 | |

mbed_official | 76:aeb1df146756 | 51 | register to their reset values. |
mbed_official | 76:aeb1df146756 | 52 | A backup domain reset is generated when one of the following events |
mbed_official | 76:aeb1df146756 | 53 | occurs: |
mbed_official | 76:aeb1df146756 | 54 | (#) Software reset, triggered by setting the BDRST bit in the |
mbed_official | 76:aeb1df146756 | 55 | RCC Backup domain control register (RCC_BDCR). You can use the |
mbed_official | 76:aeb1df146756 | 56 | RCC_BackupResetCmd(). |
mbed_official | 76:aeb1df146756 | 57 | (#) VDD or VBAT power on, if both supplies have previously been |
mbed_official | 76:aeb1df146756 | 58 | powered off. |

mbed_official | 76:aeb1df146756 | 63 | registers) is protected against possible unwanted write accesses. |
mbed_official | 76:aeb1df146756 | 64 | [..] To enable access to the Backup Domain and RTC registers, proceed as follows: |
mbed_official | 76:aeb1df146756 | 65 | (#) Enable the Power Controller (PWR) APB1 interface clock using the |
mbed_official | 76:aeb1df146756 | 66 | RCC_APB1PeriphClockCmd() function. |

mbed_official | 76:aeb1df146756 | 282 | |
mbed_official | 76:aeb1df146756 | 283 | [..] This section provide functions allowing to initialize and configure the RTC |
mbed_official | 76:aeb1df146756 | 284 | Prescaler (Synchronous and Asynchronous), RTC Hour format, disable RTC registers |
mbed_official | 76:aeb1df146756 | 285 | Write protection, enter and exit the RTC initialization mode, RTC registers |
mbed_official | 76:aeb1df146756 | 286 | synchronization check and reference clock detection enable. |
mbed_official | 76:aeb1df146756 | 287 | |
mbed_official | 76:aeb1df146756 | 288 | (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base. |
mbed_official | 76:aeb1df146756 | 289 | It is split into 2 programmable prescalers to minimize power consumption. |
mbed_official | 76:aeb1df146756 | 290 | (++) A 7-bit asynchronous prescaler and A 13-bit synchronous prescaler. |
mbed_official | 76:aeb1df146756 | 291 | (++) When both prescalers are used, it is recommended to configure the |
mbed_official | 76:aeb1df146756 | 292 | asynchronous prescaler to a high value to minimize consumption. |
mbed_official | 76:aeb1df146756 | 293 | (#) All RTC registers are Write protected. Writing to the RTC registers |
mbed_official | 76:aeb1df146756 | 294 | is enabled by writing a key into the Write Protection register, RTC_WPR. |
mbed_official | 76:aeb1df146756 | 295 | (#) To Configure the RTC Calendar, user application should enter |
mbed_official | 76:aeb1df146756 | 296 | initialization mode. In this mode, the calendar counter is stopped |
mbed_official | 76:aeb1df146756 | 297 | and its value can be updated. When the initialization sequence is |
mbed_official | 76:aeb1df146756 | 298 | complete, the calendar restarts counting after 4 RTCCLK cycles. |
mbed_official | 76:aeb1df146756 | 299 | (#) To read the calendar through the shadow registers after Calendar |
mbed_official | 76:aeb1df146756 | 300 | initialization, calendar update or after wakeup from low power modes |
mbed_official | 76:aeb1df146756 | 301 | the software must first clear the RSF flag. The software must then |
mbed_official | 76:aeb1df146756 | 302 | wait until it is set again before reading the calendar, which means |
mbed_official | 76:aeb1df146756 | 303 | that the calendar registers have been correctly copied into the |
mbed_official | 76:aeb1df146756 | 304 | RTC_TR and RTC_DR shadow registers.The RTC_WaitForSynchro() function |
mbed_official | 76:aeb1df146756 | 305 | implements the above software sequence (RSF clear and RSF check). |
