5. Electrical Characteristics

NOTES:

1.

When using the Timer C input capture mode, adjust the cycle time (1/Timer C count source frequency x 3) or above.

2.

When using the Timer C input capture mode, adjust the width (1/Timer C count source frequency x 1.5) or above.

NOTES:

1.

When selecting the digital filter by the INT0 input filter select bit, use the INT0 input HIGH width to the greater value, either

(1/digital filter clock frequency x 3) or the minimum value of standard.

2.

When selecting the digital filter by the INT0 input filter select bit, use the INT0 input LOW width to the greater value, either

(1/digital filter clock frequency x 3) or the minimum value of standard.
