Note: When an IRQ pin is set for level input (IRQnS1 = 1), the interrupt source is held until the
10.3.3
INTPRI is a 32-bit readable/writable register used to set the priorities of IRQ[7:0] (as levels from
15 to 0). These settings are only valid for IRQ/IRL7 to IRQ/IRL4 or IRQ/IRL3 to IRQ/IRL0 when
set up as individual IRQ interrupts by setting the IRLM0 or IRLM1 bit in ICR0 to 1.
Interrupt priorities should be established by setting values from H'F to H'1 in each of the 4-bit
fields. A larger value corresponds to a higher priority. When the value H'0 is set in a field, the
corresponding interrupt is masked (initial value).

CPU accepts the interrupt (this is also true for other interrupts). Therefore, even if an
interrupt source is disabled before this LSI returns from sleep mode, branching of
processing to the interrupt handler when this LSI returns from sleep mode is guaranteed. A
held interrupt can be cleared by setting the corresponding interrupt mask bit (the IM bit in
the interrupt mask register) to 1.
