For microwire EEPROMs, under the read cycle section in the description of the timing chart listed in the datasheet, if '1' is input even after multiple '0' it becomes the start bit (after CS rise), so how many times does '0' need to be entered?
There is no need to enter '0'. No matter how many times '0' is entered first, it becomes invalid and the first '1' input is recognized as the start bit.
