Because the oscillator is stopped in STOP mode, a restart delay may be imposed to
allow oscillator stabilization upon leaving STOP. If the internal oscillator is being used,
this delay is required; however, if a stable external oscillator is being used, the DLY
control bit can be used to bypass this start-up delay. The DLY control bit is set by reset
and can be optionally cleared during initialization. If the DLY equal to zero option is
used to avoid start-up delay on recovery from STOP, then reset should not be used as
the means of recovering from STOP, as this causes DLY to be set again by reset, im-
posing the restart delay. This same delay also applies to power-on reset, regardless
of the state of the DLY control bit, but does not apply to a reset while the clocks are
running.
