D.C. Electrical Characteristics, continued
Notes:
*1. RST pin is a Schmitt trigger input.
*3. P0, ALE and PSEN are tested in the external access mode.
*4. XTAL1 is a CMOS input.
*5. Pins of P1, P2, P3 , P4 can source a transition current when they are being externally driven from 1 to 0. The transition current
