mbed_official | 235:685d5f11838f | 17 | ============================================================================== |
mbed_official | 235:685d5f11838f | 18 | ##### Backup Domain Operating Condition ##### |
mbed_official | 235:685d5f11838f | 19 | ============================================================================== |
mbed_official | 235:685d5f11838f | 20 | [..] The real-time clock (RTC), the RTC backup registers, and the backup |
mbed_official | 235:685d5f11838f | 21 | SRAM (BKP SRAM) can be powered from the VBAT voltage when the main |
mbed_official | 235:685d5f11838f | 22 | VDD supply is powered off. |
mbed_official | 235:685d5f11838f | 23 | To retain the content of the RTC backup registers, backup SRAM, and supply |
mbed_official | 235:685d5f11838f | 24 | the RTC when VDD is turned off, VBAT pin can be connected to an optional |
mbed_official | 235:685d5f11838f | 25 | standby voltage supplied by a battery or by another source. |
mbed_official | 235:685d5f11838f | 26 | |
mbed_official | 235:685d5f11838f | 27 | [..] To allow the RTC operating even when the main digital supply (VDD) is turned |
mbed_official | 235:685d5f11838f | 28 | off, the VBAT pin powers the following blocks: |
mbed_official | 235:685d5f11838f | 29 | (#) The RTC |
mbed_official | 235:685d5f11838f | 30 | (#) The LSE oscillator |
mbed_official | 235:685d5f11838f | 31 | (#) The backup SRAM when the low power backup regulator is enabled |
mbed_official | 235:685d5f11838f | 32 | (#) PC13 to PC15 I/Os, plus PI8 I/O (when available) |
mbed_official | 235:685d5f11838f | 33 | |
mbed_official | 235:685d5f11838f | 34 | [..] When the backup domain is supplied by VDD (analog switch connected to VDD), |
mbed_official | 235:685d5f11838f | 35 | the following pins are available: |
mbed_official | 235:685d5f11838f | 36 | (#) PC14 and PC15 can be used as either GPIO or LSE pins |
mbed_official | 235:685d5f11838f | 37 | (#) PC13 can be used as a GPIO or as the RTC_AF1 pin |
mbed_official | 235:685d5f11838f | 38 | (#) PI8 can be used as a GPIO or as the RTC_AF2 pin |
mbed_official | 235:685d5f11838f | 39 | |
mbed_official | 235:685d5f11838f | 40 | [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT |
mbed_official | 235:685d5f11838f | 41 | because VDD is not present), the following pins are available: |
mbed_official | 235:685d5f11838f | 42 | (#) PC14 and PC15 can be used as LSE pins only |
mbed_official | 235:685d5f11838f | 43 | (#) PC13 can be used as the RTC_AF1 pin |
mbed_official | 235:685d5f11838f | 44 | (#) PI8 can be used as the RTC_AF2 pin |
mbed_official | 235:685d5f11838f | 45 | |
mbed_official | 235:685d5f11838f | 46 | ##### Backup Domain Reset ##### |
mbed_official | 235:685d5f11838f | 47 | ================================================================== |
mbed_official | 235:685d5f11838f | 48 | [..] The backup domain reset sets all RTC registers and the RCC_BDCR register |
mbed_official | 235:685d5f11838f | 49 | to their reset values. The BKPSRAM is not affected by this reset. The only |
mbed_official | 235:685d5f11838f | 50 | way to reset the BKPSRAM is through the Flash interface by requesting |
mbed_official | 235:685d5f11838f | 51 | a protection level change from 1 to 0. |
mbed_official | 235:685d5f11838f | 52 | [..] A backup domain reset is generated when one of the following events occurs: |
mbed_official | 235:685d5f11838f | 53 | (#) Software reset, triggered by setting the BDRST bit in the |
mbed_official | 235:685d5f11838f | 54 | RCC Backup domain control register (RCC_BDCR). |
mbed_official | 235:685d5f11838f | 55 | (#) VDD or VBAT power on, if both supplies have previously been powered off. |
mbed_official | 235:685d5f11838f | 56 | |
mbed_official | 235:685d5f11838f | 57 | ##### Backup Domain Access ##### |
mbed_official | 235:685d5f11838f | 58 | ================================================================== |
mbed_official | 235:685d5f11838f | 59 | [..] After reset, the backup domain (RTC registers, RTC backup data |
mbed_official | 235:685d5f11838f | 60 | registers and backup SRAM) is protected against possible unwanted write |
mbed_official | 235:685d5f11838f | 61 | accesses. |
mbed_official | 235:685d5f11838f | 62 | [..] To enable access to the RTC Domain and RTC registers, proceed as follows: |
mbed_official | 235:685d5f11838f | 63 | (+) Enable the Power Controller (PWR) APB1 interface clock using the |
mbed_official | 235:685d5f11838f | 64 | __PWR_CLK_ENABLE() function. |
mbed_official | 235:685d5f11838f | 65 | (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function. |
mbed_official | 235:685d5f11838f | 66 | (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function. |
mbed_official | 235:685d5f11838f | 67 | (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function. |
mbed_official | 235:685d5f11838f | 68 | |
mbed_official | 235:685d5f11838f | 69 | |
mbed_official | 235:685d5f11838f | 70 | ##### How to use this driver ##### |
mbed_official | 235:685d5f11838f | 71 | ================================================================== |
mbed_official | 235:685d5f11838f | 72 | [..] |
mbed_official | 235:685d5f11838f | 73 | (+) Enable the RTC domain access (see description in the section above). |
mbed_official | 235:685d5f11838f | 74 | (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour |
mbed_official | 235:685d5f11838f | 75 | format using the HAL_RTC_Init() function. |
mbed_official | 235:685d5f11838f | 76 | |
mbed_official | 235:685d5f11838f | 77 | *** Time and Date configuration *** |
mbed_official | 235:685d5f11838f | 78 | =================================== |
mbed_official | 235:685d5f11838f | 79 | [..] |
mbed_official | 235:685d5f11838f | 80 | (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime() |
mbed_official | 235:685d5f11838f | 81 | and HAL_RTC_SetDate() functions. |
mbed_official | 235:685d5f11838f | 82 | (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions. |
mbed_official | 235:685d5f11838f | 83 | |
mbed_official | 235:685d5f11838f | 84 | *** Alarm configuration *** |
mbed_official | 235:685d5f11838f | 85 | =========================== |
mbed_official | 235:685d5f11838f | 86 | [..] |
mbed_official | 235:685d5f11838f | 87 | (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function. |
mbed_official | 235:685d5f11838f | 88 | You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function. |
mbed_official | 235:685d5f11838f | 89 | (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function. |
mbed_official | 235:685d5f11838f | 90 | |
mbed_official | 235:685d5f11838f | 91 | ##### RTC and low power modes ##### |
mbed_official | 235:685d5f11838f | 92 | ================================================================== |
mbed_official | 235:685d5f11838f | 93 | [..] The MCU can be woken up from a low power mode by an RTC alternate |
mbed_official | 235:685d5f11838f | 94 | function. |
mbed_official | 235:685d5f11838f | 95 | [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B), |
mbed_official | 235:685d5f11838f | 96 | RTC wakeup, RTC tamper event detection and RTC time stamp event detection. |
mbed_official | 235:685d5f11838f | 97 | These RTC alternate functions can wake up the system from the Stop and |
mbed_official | 235:685d5f11838f | 98 | Standby low power modes. |
mbed_official | 235:685d5f11838f | 99 | [..] The system can also wake up from low power modes without depending |
mbed_official | 235:685d5f11838f | 100 | on an external interrupt (Auto-wakeup mode), by using the RTC alarm |
mbed_official | 235:685d5f11838f | 101 | or the RTC wakeup events. |
mbed_official | 235:685d5f11838f | 102 | [..] The RTC provides a programmable time base for waking up from the |
mbed_official | 235:685d5f11838f | 103 | Stop or Standby mode at regular intervals. |
mbed_official | 235:685d5f11838f | 104 | Wakeup from STOP and STANDBY modes is possible only when the RTC clock source |
mbed_official | 235:685d5f11838f | 105 | is LSE or LSI. |

mbed_official | 235:685d5f11838f | 170 | [..] This section provides functions allowing to initialize and configure the |
