Value (H) Description
Value (H)
The Oscillator Divide register (OSCDIV) provides the value to divide the system clock by.
The Oscillator Divide register must be unlocked before writing. Writing the two-step
sequence
The register locks after completion of a register write to the OSCDIV.

Oscillator Divide
00H - divider is disabled, all other entries are the divide value for scaling the
system clock.
Description
WDT Oscillator Failure Detection Enable
Failure detection of WDT oscillator is disabled.This bit is
automatically 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 enabl ed. 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.
