‡ Input pins. Output parameters in the table do not apply.
† Output pins. Input parameters in the table do not apply.
* DACSCL and I2C_CLK have different values for IOL and IOH:
DACSCL: IOL=14mA, IOH=5.8mA
I2C_CLK: IOL=9.5mA, IOH=3.2mA
Other numbers in this tables are applicable to the two signals.
