Note 1: fc: High-frequency clock [Hz], *: Don’t care
Note 2: When the system clock frequency is switched between high and low or when the external interrupt control register
(EINTCR) is overwritten, the noise canceller may not operate normally. It is recommended that external interrupts are dis-
abled using the interrupt enable register (EIR).
Note 3: The maximum time from modifying INT1NC until a noise reject time is changed is 2⁶/fc.
