IRQn Sense Select (n = 0 to 7)
Selects whether interrupt signals to the IRQ7/
IRL7
to
IRQ0/
IRL0
pins are detected at the rising edge, falling
edge, high level, or low level.
00: Interrupt requests are detected at the falling edge
of IRQn input
01: Interrupt requests are detected at the rising edge
of IRQn input
10: Interrupt requests are detected at the low level of
IRQn input
11: Interrupt requests are detected at the high level of
IRQn input

Reserved
These bits are always read as 0. The write value
should always be 0.
Note: When the IRQ is set as level input (IRQnS1 = 1), an interrupt source is held until the CPU
accepts an interrupt (not always IRQ). Therefore even if an interrupt source is disabled
before this LSI returns from sleep mode, it is guaranteed that processing is branched to the
interrupt handler when this LSI returns from sleep mode. The held interrupt can be cleared
by setting the corresponding interrupt mask bit (the IM bit in the interrupt mask register) to
1.
9.3.3 Interrupt
Priority Register (INTPRI)
INTPRI is a 32-bit readable/writable register that sets the IRQ[7:0] interrupt priorities (levels 15 to
0). This setting is valid only when using IRQ7/
IRL7
to IRQ4/
IRL4
and IRQ3/
IRL3
to IRQ0/
IRL0
as IRQ independent interrupts input to set the IRLM0 and IRLM1 bits to 1 in ICR0.
