28 / 496 page  PIC18F6585/8585/6680/8680 DS30491C-page 26 2004 Microchip Technology Inc. 2.6 Oscillator Switching Feature The PIC18F6585/8585/6680/8680 devices include a feature that allows the system clock source to be switched from the main oscillator to an alternate low-frequency clock source. For the PIC18F6585/8585/6680/8680 devices, this alternate clock source is the Timer1 oscillator. If a low-frequency crystal (32 kHz, for example) has been attached to the Timer1 oscillator pins and the Timer1 oscillator has been enabled, the device can switch to a low-power execution mode. Figure 2-7 shows a block diagram of the system clock sources. The clock switching feature is enabled by programming the Oscillator Switching Enable (OSCSEN) bit in configuration register, CONFIG1H, to a ‘0’. Clock switching is disabled in an erased device. See Section 12.0 “Timer1 Module” for further details of the Timer1 oscillator. See Section 24.0 “Special Features of the CPU” for configuration register details.
