EINTCR
(00037H)
Note 1: fc: High-frequency clock [Hz], *: Don’t care
Note 2: Edge detection during switching edge selection is invalid.
Note 3: Do not change EINTCR only when IMF = 0. After changing EINTCR, interrupt latches of external interrupt inputs
Note 4: In order to change of external interrupt input by rewriting the contents of INT2ES and INT3ES and INT4ES

must be cleared to “0” using load instruction.
during NORMAL 1/2 mode, clear interrupt latches of external interrupt inputs (INT2 and INT3 and INT4) after 8
machine cycles from the time of rewriting. During SLOW mode, 3 machine cycles are required.
