When any one of the seven INTOSC frequencies
is enabled by the following conditions, it is possible
for the oscillator to overshoot the selected
frequency:
1. A clock switch from INTRC (31 kHz) to an
2. Exit from Sleep mode with the IRCF bits
3. Executing a clock source switch via the SCS
If the selected frequency is 8 MHz, then the
Voltage versus Frequency specification of the
device may be violated.
Work around
When it is required for the application to run at
8 MHz, it is recommended that the application
does not start executing code at 8 MHz until the
60 ms firmware delay (see issue
completed. During the 60 ms settling period, the
application can execute code up to 4 MHz. Upon
completion of the 60 ms firmware delay, the 8 MHz
can be selected via the IRCF bits.
