sequence leading to normal service of the XIRQ request. If X is set to one (XIRQ masked or
inhibited), then processing will continue with the instruction which immediately follows the STOP
instruction, and no XIRQ interrupt service will be requested or pending.
Since the oscillator is stopped in STOP mode, a restart delay may be imposed to allow oscillator
stabilization upon leaving the STOP mode. If the internal oscillator is being used, this delay is
required; however,if a stable external oscillator is being used, the DLY control bit may be used to
by-pass this start-up delay. The DLY control bit is set by reset and may 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 since this will cause DLY to
be set again by reset and the restart delay will be imposed. 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.
