Any interrupt request sent by a periphery cell while the corresponding mask is not set will not be stored in the
interrupt request register. All interrupt requests are stored in their IRQxx registers depending only on their
corresponding mask setting and not on the general interrupt enable status. Whenever the EM6520 goes into
HALT Mode the IntEn bit is automatically set to 1, thus allowing to resume from Halt Mode with an interrupt.
