NOTES:

1. Testing performed at 4 MHz, however, the device is static by design and typically operates below 1 Hz.

2. Typical specifications, not guaranteed.

3. Assuming back-to-back bus cycles.

4. 8-bit bus only.

5. If wait states are used, add 2TOSC x n = number of wait states. If mode 0 (1 automatic wait state added)

operation is selected, add 2TOSC to specification.

6. TOFD is the time for the oscillator fail detect circuit (OFD) to react to a clock failure. The OFD circuitry is

enabled by programming the UPROM location 0778H with the value 0004H. Programming the CDE bit

enables oscillator fail detection.
