PIC12F683
3.6.6
The Oscillator Start-up Timer (OST) is used to ensure
that a stable system clock is provided to the device.
The OST is activated following a POR or a wake-up
from Sleep mode and the system clock is configured for
LP, XT, or HS.
Table 3-3 shows examples where the oscillator delay is
invoked.

Following a wake-up from Sleep mode or
POR, CPU start-up is invoked to allow the
CPU to become ready for code execution.
