Abstract
Alternate sideband signaling in a Peripheral Component Interconnect (PCI) express (PCIE) link may be enabled over existing sideband lines in a conventional PCIE link. For example, the default sideband communication of PCIE may be changed to a Universal Asynchronous receiver/transmitter (UART), line multiplex UART (LM-UART), serial peripheral interface (SPI), I2C, or I3C mode of communication. This change may be negotiated between the host and slave of the communication link, with a transition occurring after the negotiation concludes. The new mode of communication may include or encode the conventional PCIE sideband signals.
