Notes:
1. /RST pin is a Schmitt trigger input.
2. XTAL1 is a CMOS input.
3. Pins of P0, P1, P2, P3 and P4 can source a transition current when they are being externally driven from 1 to 0. In the condition of V
DD
=5.5V, 5he transition current reaches its
maximum value when Vin approximates to 2V .
