those two modules have the same priority. A reset initializes IPRA–IPRE to H'0000. These
registers are not initialized in standby mode.
5.3.2
ICR is a 16-bit register that sets the input detection mode of external interrupt input pins NMI and
IRQ0–IRQ7, and indicates the input signal level at the NMI pin. A reset initializes ICR but
standby mode does not.
Note: * When NMI input is high: 1; when NMI input is low: 0

NMI Edge Select (NMIE): NMIE selects whether the falling or rising edge of the
NMI input level (NMIL): NMIL sets the level of the signal input at the NMI pin. NMIL
