Notes:

If the mode bits=AXh (where X is don’t care), it will keep executing the AX read mode (without command). Only

when the mode bits are different from AXh, the device exits the AX read operation.

2. Number of dummy cycles depends on clock speed. Detailed information in Table 6.11 Read Dummy Cycles.

3. Sufficient dummy cycles are required to avoid I/O contention. If the number of dummy cycles and AX bits cycles

are same, then X should be Hi-Z.
