External Interrupt Control Register
EINTCR
(0037H)
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
Note 3: The maximum time from modifying INT1NC until a noise reject time is changed is 2
Note 4: In case
Note 5: In case
(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).
