摘要
In an aspect, an integrated circuit obtains a set of general purpose input/output (GPIO) signals for one or more peripheral devices, obtains a first virtual GPIO packet that includes the set of GPIO signals independent of a central processing unit, and transmits the first virtual GPIO packet to the one or more peripheral devices over an I3C bus independent of the central processing unit. The integrated circuit may further obtain a set of configuration signals for configuring one or more GPIO pins of the one or more peripheral devices, obtain a second virtual GPIO packet that includes the set of configuration signals independent of the central processing unit, and transmit the second virtual GPIO packet to the one or more peripheral devices over the I3C bus independent of the central processing unit.
