Copy IC PIC16LF677 Program memory after crack microcontroller PIC16LF677 protection system, and then recover the code from embedded mcu;
Two-Speed Start-up mode is entered after:
- Power-on Reset (POR) and, if enabled, after
Power-up Timer (PWRT) has expired, or when extract mcu pic16lf628a code
- Wake-up from Sleep.
If the external clock oscillator is configured to be anything other than LP, XT or HS mode, then Two-speed Start-up is disabled. This is because the external clock oscillator does not require any stabilization time after POR or an exit from Sleep.
Wake-up from Power-on Reset or Sleep.
Instructions begin execution by the internal oscillator at the frequency set in the IRCF<2:0> bits of the OSCCON register.
OST enabled to count 1024 clock cycles.
OST timed out, wait for falling edge of the internal oscillator before copy mcu pic16f819 software;
OSTS is set.
System clock held low until the next falling edge of new clock (LP, XT or HS mode).
System clock is switched to external clock source.
Checking the state of the OSTS bit of the OSCCON register will confirm if the microcontroller is running from the external clock source, as defined by the FOSC<2:0> bits in the Configuration Word register (CONFIG), or the internal oscillator.
The Fail-Safe Clock Monitor (FSCM) allows the device to continue operating should the external oscillator fail. The FSCM can detect oscillator failure any time after the Oscillator Start-up Timer (OST) has expired when copy ic pic16f873a eeprom.
The FSCM is enabled by setting the FCMEN bit in the Configuration Word register (CONFIG). The FSCM is applicable to all external Oscillator modes (LP, XT, HS, EC, RC and RCIO).
