Section 8 Interrupt Controller (INTC)
As shown in table 8.5, on-chip peripheral module or IRQ interrupts are assigned to four 4-bit
groups in each register. These 4-bit groups (bits 15 to 12, bits 11 to 8, bits 7 to 4, and bits 3 to 0)
are set with values from H'0 (0000) to H'F (1111). Setting H'0 means priority level 0 (masking is
requested); H'F means priority level 15 (the highest level).
8.4.2
ICR0 is a register that sets the input signal detection mode of external interrupt input pin NMI, and
indicates the input signal level at the NMI pin. This register is initialized to H'0000 or H'8000 by a
power-on reset or manual reset, but is not initialized in standby mode.

Description
NMI Input Level
Sets the level of the signal input at the NMI pin.
This bit can be read from to determine the NMI
pin level. This bit cannot be modified.
0 : NMI input level is low
1 : NMI input level is high
Reserved
These bits are always read as 0. The write value
should always be 0.
NMI Edge Select
Selects whether the falling or rising edge of the
interrupt request signal at the NMI pin is
detected.
0 : Interrupt request is detected on falling edge
1 : Interrupt request is detected on rising edge of
of NMI pin input
