NOTES:
1. Parameters are valid over operating temperature range unless otherwise specified.
2. Load capacitance for port 0, ALE, and PSEN = 50pF, load capacitance for all other outputs = 40pF.
3. Interfacing the 8XCL410 to devices with float time up to 75ns is permitted. This limited bus connection will not cause damage to port 0
drivers.
