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