About I2C Speed of PAC1934

Do you know PAC1934 support I2C standard mode [100Kbit / sec] and fast mode [400Kbit / sec]?

    It's right on the product page "I2C® Fast Mode Plus (1Mp/S) and SMBus 3.0". In SMBus mode the minimum data rate is 10Kb/s. Per the datasheet the minimum is "If Time-Out function is enabled, the minimum frequency for SMBus communications is 10 kHz. If Time-Out function is disabled (default condition), then there is no minimum frequency for SMBus communications"

    No, he's saying the opposite. It supports everything up to 1 megabit per second.
    Most of his post is about the minimum speed, which is only relevant in SMBUS mode.
