Claim 11:
12. The system of claim 9, wherein the second integrated circuit is further configured to send, to the first integrated circuit via the second set of transmit pins, a different indication to enter a different test mode;
wherein the first integrated circuit is further configured to:
in response to the different indication, enable a second subset of the particular set of switch circuits, wherein the second subset of switch circuits couples a second subset of the first set of receive pins to a second subset of the first set of transmit pins, and wherein the second subset of switch circuits is selected based on the different test mode, and wherein a mapping of the second subset of the first set of receive pins to the second subset of the first set of transmit pins is different than a mapping used in the particular test mode.
