主权项

1. A method comprising:
receiving a read transfer request to read data from a register of a peripheral component coupled to a bus; determining that the request indicates a subsize access of the register; asserting one or more of a plurality of strobe signals on the bus to indicate that a portion of the register has valid data to be read, wherein the plurality of strobe signals indicate byte lanes to use during a read transfer on the bus; and transferring the valid data over the bus.
