21.9.2 Interrupt servicing
0 to 4).
Because clearing an interrupt source by the UF0ICn register is given a lower priority than setting an interrupt source by
hardware, the interrupt source may not be cleared depending on the timing (n = 0 to 4).

The following flowchart illustrates how an interrupt is serviced.
The following bits of the UF0ISn register are automatically cleared by hardware when a given condition is satisfied (n =
• E0INDT, E0ODT, SUCES, STG, and CPUDEC bits of UF0IS1 register
• BKI2DT, BKI1DT, and IT1DT bits of UF0IS2 register
• BKO2FL, BKO2DT, BKO1FL, and BKO1DT bits of UF0IS3 register
