Block Diagram of DTP/External Interrupt Circuit
DTP/External Interrupt Input Detection Circuit
If a signal input to the external interrupt input pin matches the level set in the request level setting register
(ELVR) or edge, the DTP/external interrupt factor flag bit (EIRR : ER3 to ER0) corresponding to the external
interrupt input pin is set to “1”.
Request Level Setting Register (ELVR)
The interrupt request detection conditions (level or edge) are set for each external interrupt input pin
DTP/External Interrupt Factor Register (EIRR)
Stores and clears interrupt factors
DTP/External Interrupt Enable Register (ENIR)
Interrupt requests are enabled/disabled for each external interrupt input pin.
