Resets and Interrupts
Low power operation
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, imposing 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.
