Note 2: X: Don’t care, –: No change
Note 3: See electrical characteristics in section 4 for external interrupt input pulse width.
Note 4: In port setting, if 16 bit timer input is selected and capture control is executed, INT6 and
INT7 don’t depend on IIMC1 register setting. INT6 and INT7 operate by setting
TBnMOD<TBnCPM1: 0>.
