Notes:
1. Pins of P1, P2 and P3 source a transition current when they are being externally driven from 1 to 0. The transition current
reaches its maximum value when V
IN
is approximately 2V.
2. RST pin has an internal pull-down resistor.
3. P0, ALE, PSEN are in the external access mode.
4. XTAL1 is a CMOS input and RST is a Schmitt trigger input.
