The Timer1 oscillator should already be running prior to entering SEC_RUN mode which is necessary for Microchip PIC18F2553 MCU Heximal Recovering. If the T1OSCEN bit is not set when the SCS1:SCS0 bits are set to ‘01’, entry to SEC_RUN mode will not occur for Microchip PIC18F2520 Embedded Firmware Extraction. If the Timer1 oscillator is enabled, but not yet running, device clocks will be delayed until the oscillator has started. In such situa- tions, initial oscillator operation is far from stable and unpredictable operation may result.

On transitions from SEC_RUN to PRI_RUN mode, the peripherals and CPU continue to be clocked from the Timer1 oscillator while the primary clock is started. When the primary clock becomes ready, a clock switch back to the primary clock occurs (see below Figure). When the clock switch is complete, the T1RUN bit is cleared, the OSTS bit is set and the primary clock is providing the clock to Microchip MCU PIC16F870 Heximal Code Restoration. The IDLEN and SCS bits are not affected by the wake-up; the Timer1 oscillator continues to run.

In RC_RUN mode, the CPU and peripherals are clocked from the internal oscillator block using the INTOSC multiplexer. In this mode, the primary clock is shut down in order to Recover Freescale MCU MC9S12XDG128 Memory Program. When using the INTRC source, this mode provides the best power conservation of all the Run modes, while still executing code in the process of Microchip PIC18F2553 MCU Heximal Recovering. It works well for user applications which are not highly timing sensitive or do not require high-speed clocks at all times.

If the primary clock source is the internal oscillator block (either INTRC or INTOSC), there are no distinguishable differences between PRI_RUN and RC_RUN modes during MCU Crack execution. However, a clock switch delay will occur during entry to and exit from RC_RUN mode which can be carried out by Reverse Engineering Microchip PIC16F1913 Memory. Therefore, if the primary clock source is the internal oscillator block, the use of RC_RUN mode is not recommended.
