For example, if you run 12MHz APBX clock, and set HIGH_COUNT to 60, the I2C clock will have 60 cycle x (1/12MHz) = 5us time for its high period. -- Regards, Shawn -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
