AUX BIAS Control

On processor which support integrated USB Type-C* subsystem, the AUX BIAS control is required on the USB Type-C implementation (without retimer) for orientation connections. The functionality is muxed with certain GPIO pins. Refers to the GPIO implementation document for more information on the muxing and supported GPIO pin on the specific platform. In order to use the GPIO pin correctly for AUX BIAS control, the correct native functionality need to be configured and the correct Virtual Wire Index bit position need to be programmed in the BIOS policy.

GPIO - Virtual Wire Index Bit Mapping

Notes:

  1. The bit position corresponds to each corresponding GPIO pin in the group.

    For example: the bit position for USB-C_​GPP_​C0 is bit 0h in Virtual Wire Index 10h.
