The request level setting register (ELVR) selects the level or edge of the signal input to
each DTP/external interrupt pin that is to be detected as a DTP/external interrupt cause.

selection bits
•
Each of these bits selects the level or edge of the signal input to the DTP/
external interrupt pin to be detected as a DTP/external interrupt cause.
•
Two bits are assigned to each pin.
(Reference)
If the selected detection signal is input to a DTP/external interrupt pin, the
external interrupt request flag bit is set to "1" regardless of the settings of the
DTP/interrupt enable register (ENIR).
