274 @discussion IOFramebuffer subclasses may optionally implement this method to perform I2C bus requests on one of the buses they support. Alternatively they may implement the setDDCClock(), setDDCData(), readDDCClock(), readDDCData() methods and respond from getAttributeForConnection() to the kConnectionSupportsLLDDCSense attribute with success, in which case IOFramebuffer::doI2CRequest() will carry out a software implementation of I2C using the low level routines and conforming to the timing constraints passed in the timing parameter. Subclasses may pass timing parameters tuned for the specific bus, otherwise VESA DDC defaults will apply.

648 kConnectionSupportsLLDDCSense If the framebuffer wishes to make use of IOFramebuffer::doI2CRequest software implementation of I2C it should implement the I2C methods setDDCClock(), setDDCData(), readDDCClock(), readDDCData(), and it should return success (and no value) for this attribute.<br>
732 @discussion Framebuffers making use of the IOFramebuffer::doI2CRequest() software implementation of I2C should implement this method to set the state of the I2C clock line on the given bus. Otherwise may be unimplemented.
