Replicating Locked PIC12F635 Microprocessor Flash Code

Replicating Locked PIC12F635 Microprocessor Flash Code is a process to read embedded program out from PIC12F635 secured MCU and then copy firmware to new microcontroller PIC12F635;

The Two-Speed Start-up feature helps to minimize the latency period from oscillator start-up to code execution by allowing the microcontroller to use the INTRC oscillator as a clock source until the primary clock source is available. It is enabled by setting the IESO bit in Configuration Register 1H (CONFIG1H<7>).

Two-Speed Start-up is available only if the primary oscil- lator mode is LP, XT, HS or HSPLL (crystal-based modes). Other sources do not require an OST start-up delay to read microcontroller pic12f509 flash heximal; for these, Two-Speed Start-up is disabled.

When enabled, Resets and wake-ups from Sleep mode cause the device to configure itself to run from the internal oscillator block as the clock source, following the time-out of the Power-up Timer after a Power-on Reset is enabled. This allows almost immediate code execution while the primary oscillator starts and the OST is running to clone microchip pic12f510 microcontroller flash program. Once the OST times out, the device automatically switches to PRI_RUN mode.
