Oscillator Configurations
The OSC2 pin is either usable as a general purpose I/O pin or is completely unusable, depending on the
Primary Oscillator mode selection (FPR<4:0>).
OSC1 pin cannot be used as an I/O pin even if the secondary oscillator or an internal clock source is
selected at all times.

17.2.2
In order to ensure that a crystal oscillator (or ceramic
resonator) has started and stabilized, an Oscillator
Start-up Timer is included. It is a simple 10-bit counter
that counts 1024 T
oscillator clock to the rest of the system. The time-out
period is designated as T
The T
to restart (i.e., on POR, BOR and wake-up from Sleep).
The Oscillator Start-up Timer is applied to the LP
oscillator, XT, XTL and HS modes (upon wake-up from
Sleep, POR and BOR) for the primary oscillator.
