3.5 External Interrupts
3. Interrupt Control Circuit
External Interrupt Control Register
EINTCR
(0037H)
Note 1: fc: High-frequency clock [Hz], *: Don’t care
Note 2: When the external interrupt control register (EINTCR) is overwritten, the noise canceller may not operate normally. It is
Note 3: The maximum time from modifying EINTCR<INT1NC> until a noise reject time is changed is 2
Note 4: In case
recommended that external interrupts are disabled using the interrupt enable register (EIR).
