Interrupts IRQ4–IRQ0 can wake the chip up from the standby state when the relevant interrupt
level is higher than the setting of I3–I0 in the SR register (but only when the RTC 32-kHz
oscillator is used).
If the IRQ edge is input immediately before the CPU enters the standby mode (during the period
between when the CPU executes a SLEEP instruction and when STATUS0 becomes high level),
the interrupt may not be detected. However, the interrupt will be accepted correctly if the IRQ
edge is re-input after the CPU has entered the standby mode (when STATUS0 is high level). In
addition, the interrupt may not be detected if the IRQ edge is input during frequency change
processing (WDT count).
6.2.3
IRL interrupts are input by level at pins IRL3–IRL0 and IRLS3–IRLS0. IRLS3–IRLS0 are
enabled when the IRQLVL bit and IRLSEN bit in interrupt control register 1 (ICR1) are both 1.
The priority level is the higher level indicated by pins IRL3–IRL0 and IRLS3–IRLS0. An IRL3–
IRL0/IRLS3–IRLS0 value of 0 (0000) indicates the highest-level interrupt request (interrupt
priority level 15). A value of 15 (1111) indicates no interrupt request (interrupt priority level 0).
Figure 6.2 shows an example of IRL interrupt connection. Table 6.3 shows IRL/IRLS pins and
interrupt levels.
