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.
Note 4: In case RESET pin is released while the state of INT3 pin keeps "H" level, the external interrupt 3 request is not generated
even if the INT3 edge select is specified as "H" level. The rising edge is needed after RESET pin is released.
Note 5: In case RESET pin is released while the state of INT4 pin keeps "H" level, the external interrupt 4 request is not generated
even if the INT4 edge select is specified as "H" level. The rising edge is needed after RESET pin is released.
