Function Documentation

int32_t XMC_ETH_PHY_ExitPowerDown	(	XMC_ETH_MAC_t *const	eth_mac,
		uint8_t	phy_addr
	)

Parameters

eth_mac	A constant pointer to XMC_ETH_MAC_t, pointing to the ETH MAC base address
phy_addr	Physical address

Returns: int32_t return status XMC_ETH_PHY_STATUS_t

Description:: Exit power down mode

XMC_ETH_LINK_DUPLEX_t XMC_ETH_PHY_GetLinkDuplex	(	XMC_ETH_MAC_t *const	eth_mac,
		uint8_t	phy_addr
	)

Parameters

eth_mac	A constant pointer to XMC_ETH_MAC_t, pointing to the ETH MAC base address
phy_addr	Physical address

Returns: XMC_ETH_LINK_DUPLEX_t ETH link duplex settings

Description:: Get link duplex settings

: The function reads the physical layer interface and returns the link duplex settings. It returns either XMC_ETH_LINK_DUPLEX_FULL or XMC_ETH_LINK_DUPLEX_HALF.

XMC_ETH_LINK_SPEED_t XMC_ETH_PHY_GetLinkSpeed	(	XMC_ETH_MAC_t *const	eth_mac,
		uint8_t	phy_addr
	)

Parameters

eth_mac	A constant pointer to XMC_ETH_MAC_t, pointing to the ETH MAC base address
phy_addr	Physical address

Returns: XMC_ETH_LINK_SPEED_t ETH link speed

Description:: Get link speed

: The function reads the physical layer interface and returns the link speed. It returns either XMC_ETH_LINK_SPEED_100M or XMC_ETH_LINK_SPEED_10M.

XMC_ETH_LINK_STATUS_t XMC_ETH_PHY_GetLinkStatus	(	XMC_ETH_MAC_t *const	eth_mac,
		uint8_t	phy_addr
	)

Parameters

eth_mac	A constant pointer to XMC_ETH_MAC_t, pointing to the ETH MAC base address
phy_addr	Physical address

Returns: XMC_ETH_LINK_STATUS_t ETH link status

Description:: Get link status

: The function reads the physical layer interface and returns the link status. It returns either XMC_ETH_LINK_STATUS_UP or XMC_ETH_LINK_STATUS_DOWN.

int32_t XMC_ETH_PHY_Init	(	XMC_ETH_MAC_t *const	eth_mac,
		uint8_t	phy_addr,
		const XMC_ETH_PHY_CONFIG_t *const	config
	)

Parameters

eth_mac	A constant pointer to XMC_ETH_MAC_t, pointing to the ETH MAC base address
phy_addr	Physical address
config	A constant pointer to XMC_ETH_PHY_CONFIG_t, pointing to a physical layer config

Returns: int32_t return status XMC_ETH_PHY_STATUS_t

Description:: Initialize the ETH physical layer interface

: The function sets the link speed, applies the duplex mode, sets auto-negotiation and loop-back settings.

bool XMC_ETH_PHY_IsAutonegotiationCompleted	(	XMC_ETH_MAC_t *const	eth_mac,
		uint8_t	phy_addr
	)

Parameters

eth_mac	A constant pointer to XMC_ETH_MAC_t, pointing to the ETH MAC base address
phy_addr	Physical address

Returns: bool True if autonegotiation process is finished otherwise false

Description:: Get status of autonegotiation

int32_t XMC_ETH_PHY_PowerDown	(	XMC_ETH_MAC_t *const	eth_mac,
		uint8_t	phy_addr
	)

Parameters
