Notes:
*1. RST pin is a Schmitt trigger input.
*2. P0, ALE and PSEN are tested in the external access mode.
*3. XTAL1 is a CMOS input.
*4. Pins of P1, P2, P3, P4 can source a transition current when they are being externally driven from 1 to 0. The transition
current reaches its maximum value when VIN approximates to 2V.
