Section 9 Interrupt Controller (INTC)
9.3.1
ICR0 is a 32-bit readable and partially writable register that sets the input signal detection mode of
the external interrupt input pins (IRQ7/IRL7 to IRQ0/IRL0) and NMI pin, and indicates the input
level to the NMI pin.

Description
NMI Input Level
Sets the signal level input to the NMI pin. Reading this
bit allows the user to know the NMI pin level, and
writing is invalid.
0: Low level is input to the NMI pin
1: High level is input to the NMI pin
MAI Interrupt Mask
Specifies whether all interrupts are masked during the
low level period of the NMI pin level regardless of the
BL bit in SR of the CPU.
0: Interrupts are enabled even if the NMI pin goes low
1: Interrupts are disabled if the NMI pin goes low
Reserved
These bits are always read as 0. The write value should
always be 0.
