Notes:
1. nRESET pin is a Schmitt trigger input.
2. Crystal Input is a CMOS input.
3. Pins of PA, PB, PC, PD and PE can source a transition current when they are being externally driven from 1 to 0. In the
condition of V
DD
=5.5 V, 5he transition current reaches its maximum value when V
IN
approximates to 2V.
