Detailed Description

Interface between SF_EL_NX Ethernet framework and PHY driver.

Function Documentation

bsp_ethernet_phy_get_autonegotiate()

int16_t bsp_ethernet_phy_get_autonegotiate	(	uint32_t	channel,
		uint16_t *	p_line_speed_duplex,
		uint16_t *	p_local_pause,
		uint16_t *	p_partner_pause
	)

Gets capabilities of an Ethernet PHY device.

Parameters

[in]	channel	Ethernet channel number
[in]	p_line_speed_duplex	A pointer to the location of both the line speed and the duplex
[in]	p_local_pause	A pointer to the location to store the local pause bits
[in]	p_partner_pause	A pointer to the location to store the partner pause bits

Return values

R_PHY_OK	Got information successfully
R_PHY_ERROR	PHY device is yet to be initialized

Note

Validating parameters is not required by this function as it by design is only called by sf_el_nx framework with valid parameters.

Reads the status register. Because reading the first time shows the previous state, the Link status bit should be read twice.

Checks the link status

Check the auto-negotiation status

Gets local pause capability

bsp_ethernet_phy_get_link_status()

int16_t bsp_ethernet_phy_get_link_status

(

uint32_t

channel

)

bsp_ethernet_phy_get_link_status - Returns the status of the physical link.

Parameters

[in]

channel

Ethernet channel number

Return values

R_PHY_OK	PHY device is initialized successfully
R_PHY_ERROR	PHY device is not initialized successfully

bsp_ethernet_phy_init()

int16_t bsp_ethernet_phy_init

(

uint32_t

channel

)

bsp_ethernet_phy_init - Initialize Ethernet PHY device.

Parameters

[in]

channel

Ethernet channel number

Return values

R_PHY_OK	PHY device is initialized successfully
R_PHY_ERROR	PHY device is not initialized successfully or Validation of PHY chip fails.

Note

Refer HW manual for valid channels for a target MCU

Read the PHY Identifier register and compare read value with the PHY chip OUI identifier number

Resets PHY device

Waits the reset completion, PHY_CONTROL_RESET bit is self-cleared after 1 is written to it.

When MICREL_KSZ8091RNB of the Micrel, Inc. is used, the pin that outputs the state of LINK is used combinedly with ACTIVITY in default. The setting of the pin is changed so that only the state of LINK is output. Set Clock Mode to 50MHz

Sets Duplex Mode as Full-duplex

bsp_ethernet_phy_start_autonegotiate()

void bsp_ethernet_phy_start_autonegotiate	(	uint32_t	channel,
		uint8_t	pause
	)

Sets Auto-Negotiation advertisement and starts auto-negotiation.

Parameters

[in]	channel	Ethernet channel number
[in]	pause	Using state of pause frames
