I've faced this same question today and correct sequence is LOW-configure-HIGH, as listed in examples, but not in that note under the table 3 in section 2.2.
In addition, this sequence is used incorrectly in the init_i2c8.sh script used to set muxing for MCU I2C access in MCU SDK (Sample scripts for the MCU SDK | Intel® Software). The script only has one line for pin 214 - and it sets it to HIGH before doing pin configurations, which is not recommended per the docs. It seems to work like that for whatever reason, but I think it would be better to align it with recommendations.
@Intel support folks, could you please take this to document and MCU SDK pin setup script maintainers?
