Abstract
A principal device includes a protocol controller coupled, via a serial bus, to one or more subordinate devices. The serial bus includes a clock wire and a data wire. The protocol controller is configured to send, on the data wire, a read command addressed to a subordinate device to initiate a read transaction. The protocol controller is also configured to modify a clock signal on the clock wire to extend a bus park cycle period. The bus park cycle period is extended based on a data preparation delay associated with the subordinate device. The protocol controller is further configured to, subsequent to the bus park cycle period, read data from the data wire during the read transaction.
