The length of the transition between clock sources is the sum of two cycles of the old clock source by Recover PIC18F2539 Microcontroller Lost Heximal File and three to four cycles of the new clock source. This formula assumes that the new clock source is stable.

Three bits indicate the current clock source and its status. They are:

• OSTS (OSCCON<3>)
• IOFS (OSCCON<2>)
• T1RUN (T1CON<6>)

In general, only one of these bits will be set while in a given power-managed mode. When the OSTS bit is set, the primary clock is providing the device clock by Break Nuvoton W78E054 MCU Flash. When the IOFS bit is set, the INTOSC output is providing a stable 8 MHz clock source to a divider that actually drives the device clock. When the T1RUN bit is set, the Timer1 oscillator is providing the clock. If none of these bits are set, then either the INTRC clock source is clocking the device, or the INTOSC source is not yet stable after Crack MCU Memory.

If the internal oscillator block is configured as the primary clock source by the FOSC3:FOSC0 Configuration bits in order to Attack Winbond W78E051A Protected Eeprom, then both the OSTS and IOFS bits may be set when in PRI_RUN or PRI_IDLE modes. This indicates that the primary clock (INTOSC output) is generating a stable 8 MHz output from Recover PIC18F2539 Microcontroller Lost Heximal File. Entering another power-managed RC mode at the same frequency would clear the OSTS bit.

Caution should be used when modifying a single IRCF bit through Reverse Engineering W78E52B Chip Data. If VDD is less than 3V, it is possible to select a higher clock speed than is supported by the low VDD. Improper device operation may result if the VDD/FOSC specifications are violated.

Executing a SLEEP instruction does not necessarily place the device into Sleep mode. It acts as the trigger to place the controller into either the Sleep mode or one of the Idle modes, depending on the setting of the IDLEN bit for the purpose of Winbond Microcontroller W78E0516 Embedded Binary Recovering.
