GPIO fixed functions (Signals for Integrated Connectivity (CNVi) and Discrete Connectivity (CNVd) functions

I/O

For CNVi: RF companion (CRF) reset signal, active low. Require a 75 kohm Pull-Down on platform/motherboard level. It is recommended not to use it for bootstrapping during early Platform init flows.

For discrete connectivity with UART host support: Optional Bluetooth* I²S bus sync

O

For CNVi: BRI bus TX.

For discrete connectivity with UART host support: Bluetooth* UART RTS#

I

For CNVi: BRI bus RX.

For discrete connectivity with UART host support: Bluetooth* UART RXD

O

For CNVi: RGI bus TX. RGI_​DT is used by the platform to strap presence of the CRF. Requires weak pull up of 20Kohm on the platform.

For discrete connectivity with UART host support: Bluetooth* UART TXD

I

For CNVi: RGI bus RX.

For discrete connectivity with UART host support: Bluetooth* UART CTS#

O

For CNVi: processor to CRF wake indication

I/O

For CNVi and discrete connectivity : Optional WLAN/Bluetooth* WWAN co-existence signal. Used to be co-existence signal for external GNSS solution

I

For CNVi and discrete connectivity: Optional WLAN/Bluetooth* WWAN co-existence signal (Input)

O

For CNVi and discrete connectivity : Optional WLAN/Bluetooth* WWAN co-existence signal (Output)
