Notes:

1. Open-drain outputs with pullups include Port 1, P2.6 and P2.7.

2. Test modes are entered at the RESET rising edge by applying V IL to one or more of the following pins: TXD, RD, WR , HLDA. To avoid entering a test mode,

ensure that these pins remain above VIH at the rising edge of RESET .

3. Inputs/outputs with pullup resistors include: RESET, Port 1, P2.0, P2.6, P2.7, WR, BHE, AD0-15, RD, ALE, CLKOUT.

4. Inputs/outputs will pulldown resistors include: NMI, HS0.0-HS0.3, P2.5, INST.

5. The ISO1 spec applies to pins RESET, BHE, RD, CLKOUT.

6. Tested only at initial qualification and after any design or process changes which may affect this characteristic.

7. Not more than one output may be shorted at a time for maximum duration of one second.

8. For standard outputs not covered by IOHI spec.
