The Timer1 oscillator is also available as a clock source in power-managed modes. By setting the System Clock Select bits, SCS1:SCS0 (OSCCON<1:0>), to ‘01’, the device switches to SEC_RUN mode; both the CPU and peripherals are clocked from the Timer1 oscillator through Extract Microprocessor PIC16C72A Heximal.

If the IDLEN bit (OSCCON<7>) is cleared and a SLEEP instruction is executed, the device enters SEC_IDLE mode. Additional details are available in Section 3.0 “Power-Managed Modes”. Whenever the Timer1 oscillator is providing the clock source when Copy Microprocessor PIC16C74B Firmware, the Timer1 system clock status flag, T1RUN (T1CON<6>), is set. This can be used to determine the controller’s current clocking mode when Copy Microchip MCU PIC16F1454 Flash Memory.

It can also indicate the clock source being currently used by the Fail-Safe Clock Monitor by Crack MCU. If the Clock Monitor is enabled and the Timer1 oscillator fails while providing the clock, polling the T1RUN bit will indicate whether the clock is being provided by the Timer1 oscillator or another source.

The oscillator circuit, shown in below Figure, should be located as close as possible to the microcontroller. There should be no circuits passing within the oscillator circuit boundaries other than VSS or VDD. If a high-speed circuit must be located near the oscillator in order to Read MCU PIC16C73B Eeprom (such as the PWM pin, or the primary oscillator using the OSC2 pin), a grounded guard ring around the oscillator circuit, as shown in Figure 12-4, may be helpful when used on a single-sided PCB, or in addition to a ground plane after Copy Microchip MCU PIC16F1454 Flash Memory.
