mbed_official | 237:f3da66175598 | 23 | =============================================================================== |
mbed_official | 237:f3da66175598 | 24 | ##### RTC Operating Condition ##### |
mbed_official | 237:f3da66175598 | 25 | =============================================================================== |
mbed_official | 237:f3da66175598 | 26 | [..] The real-time clock (RTC) and the RTC backup registers can be powered |
mbed_official | 237:f3da66175598 | 27 | from the VBAT voltage when the main VDD supply is powered off. |
mbed_official | 237:f3da66175598 | 28 | To retain the content of the RTC backup registers and supply the RTC |
mbed_official | 237:f3da66175598 | 29 | when VDD is turned off, VBAT pin can be connected to an optional |
mbed_official | 237:f3da66175598 | 30 | standby voltage supplied by a battery or by another source. |
mbed_official | 237:f3da66175598 | 31 | |
mbed_official | 237:f3da66175598 | 32 | [..] To allow the RTC to operate even when the main digital supply (VDD) |
mbed_official | 237:f3da66175598 | 33 | is turned off, the VBAT pin powers the following blocks: |
mbed_official | 237:f3da66175598 | 34 | (#) The RTC |
mbed_official | 237:f3da66175598 | 35 | (#) The LSE oscillator |
mbed_official | 237:f3da66175598 | 36 | (#) PC13 to PC15 I/Os (when available) |
mbed_official | 237:f3da66175598 | 37 | |
mbed_official | 237:f3da66175598 | 38 | [..] When the backup domain is supplied by VDD (analog switch connected |
mbed_official | 237:f3da66175598 | 39 | to VDD), the following functions are available: |
mbed_official | 237:f3da66175598 | 40 | (#) PC14 and PC15 can be used as either GPIO or LSE pins |
mbed_official | 237:f3da66175598 | 41 | (#) PC13 can be used as a GPIO or as the RTC_AF pin |
mbed_official | 237:f3da66175598 | 42 | |
mbed_official | 237:f3da66175598 | 43 | [..] When the backup domain is supplied by VBAT (analog switch connected |
mbed_official | 237:f3da66175598 | 44 | to VBAT because VDD is not present), the following functions are available: |
mbed_official | 237:f3da66175598 | 45 | (#) PC14 and PC15 can be used as LSE pins only |
mbed_official | 237:f3da66175598 | 46 | (#) PC13 can be used as the RTC_AF pin |
mbed_official | 237:f3da66175598 | 47 | |

mbed_official | 237:f3da66175598 | 49 | =============================================================================== |
mbed_official | 237:f3da66175598 | 50 | [..] The backup domain reset sets all RTC registers and the RCC_BDCR |
mbed_official | 237:f3da66175598 | 51 | register to their reset values. |
mbed_official | 237:f3da66175598 | 52 | A backup domain reset is generated when one of the following events |
mbed_official | 237:f3da66175598 | 53 | occurs: |
mbed_official | 237:f3da66175598 | 54 | (#) Software reset, triggered by setting the BDRST bit in the |
mbed_official | 237:f3da66175598 | 55 | RCC Backup domain control register (RCC_BDCR). |
mbed_official | 237:f3da66175598 | 56 | (#) VDD or VBAT power on, if both supplies have previously been |
mbed_official | 237:f3da66175598 | 57 | powered off. |

mbed_official | 237:f3da66175598 | 63 | accesses. |
mbed_official | 237:f3da66175598 | 64 | |
mbed_official | 237:f3da66175598 | 65 | [..] To enable access to the RTC Domain and RTC registers, proceed as follows: |

mbed_official | 237:f3da66175598 | 209 | ##### Initialization and de-initialization functions ##### |
mbed_official | 237:f3da66175598 | 210 | =============================================================================== |
mbed_official | 237:f3da66175598 | 211 | [..] This section provide functions allowing to initialize and configure the |
mbed_official | 237:f3da66175598 | 212 | RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable |
mbed_official | 237:f3da66175598 | 213 | RTC registers Write protection, enter and exit the RTC initialization mode, |
mbed_official | 237:f3da66175598 | 214 | RTC registers synchronization check and reference clock detection enable. |
mbed_official | 237:f3da66175598 | 215 | (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base. |
mbed_official | 237:f3da66175598 | 216 | It is split into 2 programmable prescalers to minimize power consumption. |
mbed_official | 237:f3da66175598 | 217 | (++) A 7-bit asynchronous prescaler and A 13-bit synchronous prescaler. |
mbed_official | 237:f3da66175598 | 218 | (++) When both prescalers are used, it is recommended to configure the |
mbed_official | 237:f3da66175598 | 219 | asynchronous prescaler to a high value to minimize consumption. |
mbed_official | 237:f3da66175598 | 220 | (#) All RTC registers are Write protected. Writing to the RTC registers |
mbed_official | 237:f3da66175598 | 221 | is enabled by writing a key into the Write Protection register, RTC_WPR. |
mbed_official | 237:f3da66175598 | 222 | (#) To Configure the RTC Calendar, user application should enter |
mbed_official | 237:f3da66175598 | 223 | initialization mode. In this mode, the calendar counter is stopped |
mbed_official | 237:f3da66175598 | 224 | and its value can be updated. When the initialization sequence is |
mbed_official | 237:f3da66175598 | 225 | complete, the calendar restarts counting after 4 RTCCLK cycles. |
mbed_official | 237:f3da66175598 | 226 | (#) To read the calendar through the shadow registers after Calendar |
mbed_official | 237:f3da66175598 | 227 | initialization, calendar update or after wakeup from low power modes |
mbed_official | 237:f3da66175598 | 228 | the software must first clear the RSF flag. The software must then |
mbed_official | 237:f3da66175598 | 229 | wait until it is set again before reading the calendar, which means |
mbed_official | 237:f3da66175598 | 230 | that the calendar registers have been correctly copied into the |
mbed_official | 237:f3da66175598 | 231 | RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function |
mbed_official | 237:f3da66175598 | 232 | implements the above software sequence (RSF clear and RSF check). |
