Description
Internal Precision Oscillator Enable
Internal precision oscillator is disabled.
Internal precision oscillator is enabled.
Crystal Oscillator Enable
Crystal oscillator is disabled.
Crystal oscillator is enabled.
WDT Oscillator Enable
WDT oscillator is disabled.
WDT oscillator is enabled.
Primary Oscillator Failure Detection Enable
Failure detection and recovery of primary oscillator is disabled. This bit is
cleared automatically if a primary oscillator failure is detected.
Failure detection and recovery of primary oscillator is enabled.
WDT Oscillator Failure Detection Enable
Failure detection of WDT oscillator is disabled.This bit is cleared automati-
cally if a WDT oscillator failure is detected.
Failure detection of WDT oscillator is enabled.
Flash Low Power Mode Enable
Flash Low Power Mode is disabled.
Flash Low Power Mode is enabled. The Flash will be powered down during
idle periods of the clock and powered up during Flash reads. This bit must
only be set if the frequency of the primary oscillator source is 8 MHz or lower.
The reset value of this bit is controlled by the LPOPT option bit during reset.
System Clock Oscillator Select
Internal precision oscillator functions as system clock at 5.6 MHz.
Crystal oscillator or external clock driver functions as system clock.
Reserved.
Watchdog Timer oscillator functions as system clock.
