NOTES

1 :When using the Timer C input capture mode, adjust the cycle time above ( 1/ Timer C count source

frequency x 3).

2 : When using the Timer C input capture mode, adjust the pulse width above ( 1/ Timer C count source

frequency x 1.5).

NOTES

________

________

1 : When selecting the digital filter by the INT0 input filter select bit, use the INT0 input HIGH pulse width

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