The purpose of ARM STM32F071V8 Processor Flash Program Replication is to have the microcontroller stm32f071v8 functions restoration after crack locked bit of mcu stm32f071v8 flash memory;

The system window watchdog is based on a 7-bit downcounter that can be set as free running. It can be used as a watchdog to reset the device when a problem occurs. It is clocked from the APB clock (PCLK). It has an early warning interrupt capability and the counter can be frozen in debug mode.

This timer is dedicated to real-time operating systems, but could also be used as a standard down counter when extract code from arm microcontroller stm32f070rc. It features:

• A 24-bit down counter
  • Autoreload capability
  • Maskable system interrupt generation when the counter reaches 0

Programmable clock source (HCLK or HCLK/8)

The RTC is an independent BCD timer/counter. Its main features are the following:

• Calendar with subseconds, seconds, minutes, hours (12 or 24 format), week day, date, month, year, in BCD (binary-coded decimal) format.
  • Automatic correction for 28, 29 (leap year), 30, and 31 day of the month.
  • Programmable alarm with wake up from Stop and Standby mode capability.
  • Periodic wakeup unit with programmable resolution and period.
  • On-the-fly correction from 1 to 32767 RTC clock pulses. This can be used to synchronize the RTC with a master clock.
  • Digital calibration circuit with 1 ppm resolution, to compensate for quartz crystal inaccuracy to effectively;
  • Tow anti-tamper detection pins with programmable filter. The MCU can be woken up from Stop and Standby modes on tamper event detection.
  • Timestamp feature which can be used to save the calendar content. This function can be triggered by an event on the timestamp pin, or by a tamper event. The MCU can be woken up from Stop and Standby modes on timestamp event detection.
  • Reference clock detection: a more precise second source clock (50 or 60 Hz) can be used to enhance the calendar precision.

The RTC clock sources can be:

• A 32.768 kHz external crystal
  • A resonator or oscillator
  • The internal low-power RC oscillator (typical frequency of 40 kHz)
