The Arasan I3C Secondary Controller IP Core implements Active controller functionality as defined by the MIPI Alliance’s I3C Specification and Secondary Controller logic. The I3C bus is used for various sensors in the mobile/automotive system where the active controller transfers data and control between itself and various sensor devices. In some applications, the active controllers can handoff the controller role to the secondary controller on the bus. The Dual role IP joins the I3C bus as a secondary controller (as a target) and will request/accept the controller role. The IP core provides a 32bit AHB bus as application interface to configure and control the transfers. The controller manages the control signal to IO buffers during the active and standby mode
