OSCILLATOR DELAY UPON

POWER-UP, WAKE-UP AND BASE

FREQUENCY CHANGE

In applications where the OSCTUNE register is used to

shift the frequency of the internal oscillator, it is

recommended that the application does not expect the

frequency of the internal oscillator to stabilize

immediately. In this case, the frequency may shift

gradually toward the new value. The time for this

frequency shift is less than eight cycles of the base

frequency.

On power-up, the device is held in reset by the

power-up time if the power-up timer is enabled.

Following a wake-up from Sleep mode or POR, an

internal delay of ~10 µs is invoked to allow the memory

bias to stabilize before program execution can begin.
