• Manufacturer Part Number: EM6517
• Description: 4 BIT MICROCONTROLLER
• Manufacturer: ETC

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 mask
setting and not on the general interrupt enable status.
Whenever the EM6517-1 goes into HALT Mode the IntEn bit is automatically set to 1, thus allowing to resume
from halt mode with an interrupt. This behavior is blocked if SWBAuto is set high. In this case the peripheral
interrupts are disabled until the SWBAuto bit is reset low. Please refer also to the SWB chapter 9.
