6.2
Table 6.1 lists the INTC pin configuration.
Table 6.1
6.3
There are 4 types of interrupt sources: NMI, IRQ, IRL, and on-chip peripheral modules. The
priority of each interrupt is indicated by a priority level value (16 to 0), with level 16 as the
highest and level 1 as the lowest. When level 0 is set, the interrupt is masked and interrupt
requests are ignored.
6.3.1
The NMI interrupt has the highest priority level of 16. When the BLMSK bit of the interrupt
control register (ICR1) is 1 or the BL bit of the status register (SR) is 0, NMI interrupts are
accepted when the MAI bit of the ICR1 register is 0. NMI interrupts are edge-detected. In sleep or
software standby mode, the interrupt is accepted regardless of the BL. The NMI edge select bit
(NMIE) in the interrupt control register 0 (ICR0) is used to select either the rising or falling edge.
When the NMIE bit of the ICR0 register is changed, the NMI interrupt is not detected for 20
cycles after changing the ICR0. NMIE to avoid a false detection of the NMI interrupt. NMI
interrupt exception processing does not affect the interrupt mask level bits (I3 to I0) in the status
register (SR).
When the BL bit is 1 and the BLMSK bit of the ICR1 register is set to 1, only NMI interrupts are
accepted and the SPC register and SSR register are updated by the NMI interrupt handler, making
it impossible to return to the original processing from exception processing initiated prior to the
NMI. Use should therefore be restricted to cases where return is not necessary.
