Abstract
System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within an electronic apparatus. A method performed by a slave device coupled to a serial bus includes detecting an event related to a function of the slave device, initiating a first counter in the slave device, asserting an in-band interrupt request by driving at least one signal on the serial bus, and transmitting content of the first counter to a bus master coupled to the serial bus during an interrupt handling procedure. The first counter may count cycles of a clock used by the slave device or occurrences of a signaling state or condition on the serial bus. The content of the first counter may be used to determine a time stamp for the event.
