Reverse Engineering PIC18F24K40T Microcontroller Heximal Data is a process to crack pic18f24k40t mcu security fuse bit, and then readout secured code from microprocessor pic18f24k40t flash memory;

The PIC18F24K40T devices contain circuitry to prevent clocking “glitches” when switching between clock sources. A short pause in the system clock occurs during the clock switch.

The length of this pause is between eight and nine clock periods of the new clock source. This ensures that the new clock source is stable and that its pulse width will not be less than the shortest pulse width of the two clock sources.

When the device executes a SLEEP instruction, the system is switched to one of the power managed modes, depending on the state of the IDLEN and SCS1:SCS0 bits of the OSCCON register when recover microcontroller pic18f24k20 flash program and eeprom data.

When PRI_IDLE mode is selected, the designated primary oscillator continues to run without interruption. For all other power managed modes, the oscillator using the OSC1 pin is disabled. The OSC1 pin (and OSC2 pin, if used by the oscillator) will stop oscillating.

In Secondary Clock modes (SEC_RUN and SEC_I- DLE), the Timer1 oscillator is operating and providing the system clock in the process of pic18f24k22 mcu locked code recovery. The Timer1 oscillator may also run in all power managed modes if required to clock Timer1 or Timer3.
