Function Documentation

ULPIConfigSet()

void ULPIConfigSet	(	uint32_t	ui32Base,
		uint32_t	ui32Config
	)

Sets the configuration of an external USB Phy.

Parameters

ui32Base	specifies the USB module base address.
ui32Config	specifies the configuration options for the external Phy.

This function sets the configuration options for an externally connected USB Phy that is connected using the ULPI interface. The ui32Config parameter holds all of the configuration options defined by the UPLI_CFG_ values. The values are grouped as follows:

Connection speed, using one of the following:

• UPLI_CFG_HS enables high speed operation.
• UPLI_CFG_FS enables full speed operation.
• UPLI_CFG_HS enables low speed operation.

Any of the following can be included:

• UPLI_CFG_AUTORESUME enable automatic transmission of resume signaling from the Phy.
• UPLI_CFG_INVVBUSIND inverts the external VBUS indicator if it is selected.
• UPLI_CFG_PASSTHRUIND passes the external VBUS indicator through without using the Phy's VBUS comparator.
• ULPI_CFG_EXTVBUSDRV enables an external VBUS drive source.
• ULPI_CFG_EXTVBUSIND enables an external signal for VBUS valid.

Returns

None.

ULPIPowerTransceiver()

void ULPIPowerTransceiver	(	uint32_t	ui32Base,
		bool	bEnable
	)

Enables or disables power to the external USB Phy.

Parameters

ui32Base	specifies the USB module base address.
bEnable	specifies if the Phy is fully powered or in suspend mode.

This function sets the current power configuration for the external ULPI connected Phy. When bEnable is true the Phy is fully powered and when false the USB Phy is in suspend mode.

Returns

None.
