Microcontroller STM32F042K6 Flash Locked Bit Breaking means the tamper resistance system of stm32f042k6 mcu will be cracked as well as readout protection, and then copying the heximal data to new microprocessor stm32f042k6 as mcu cloning;
The regulator has two operating modes and it is always enabled after reset.
- Main (MR) is used in normal operating mode (Run).
- Low power (LPR) can be used in Stop mode where the power demand is reduced.
In Standby mode, it is put in power down mode. In this mode, the regulator output is in high impedance and the kernel circuitry is powered down, inducing zero consumption (but the contents of the registers and SRAM are lost).
System clock selection is performed on startup, however the internal RC 8 MHz oscillator is selected as default CPU clock on reset by recover stm32f042f4 microcontroller embedded heximal program. An external 4-32 MHz clock can be selected, in which case it is monitored for failure. If failure is detected, the system automatically switches back to the internal RC oscillator.
A software interrupt is generated if enabled. Similarly, full interrupt management of the PLL clock entry is available when necessary (for example on failure of an indirectly used external crystal, resonator or oscillator).
