Notes:
*1. RST pin has an internal pull-down.
*2. Pins of P1 and P3 can source a transition current when they are being externally driven from 1 to 0.
*3. RST is a Schmitt trigger input and XTAL1 is a CMOS input.
*4. P0, P2, ALE and
PSEN
are tested in the external access mode.
*5. P3.4 to P3.7 are in normal mode.
