Tool/software:
Please ask, if an i2c slave supports standard-mode and fast-mode, and the actual master gives a 98Khz signal, at this time the timing is in accordance with which standard?
For example, I measured that the start of the set-up and hold time is only 2.5us, and the end of the set-up time is only 2.5us, then does this meet the timing requirements of slave?
