1. On a 16-bit bus, if only one byte is being written, then only one of BLE or BHE will go active. On an 8-bit bus, BLE goes active for all (odd or
2. The bus timing is designed to make meeting hold time very straightforward without glue logic. On all reads and fetches, in order to meet hold
3. To avoid 3-State fights during read cycles and fetch cycles, do not drive data bus until OE goes active
4. WARNING: ClkOut is specified at 40 pF max. More than 40 pf on ClkOut may significantly degrade the ClkOut waveform. Load capacitance
5. Not all combinations of bus timing configuration values result in valid bus cycles. Please refer to the XA-H3 User Manual for details.
6. When code is being fetched on the external bus, a burst mode fetch is used. This burst can be from 2 to 16 bytes long. On a 16-bit bus,
7. The MIN value for this parameter is guaranteed by design and is not tested in production to the specified limit. In those cases where a
