Note 1:
Absolute Maximum Ratings are those values beyond which damage to the device may occur. All voltages referenced to ground unless otherwise noted.
Note 2:
The DB0–DB3 and AD0–AD3 lines all have active P-channel pull-up transistors which will source current. The CS, RD, and WR lines have internal pull-up
resistors to V
