Detailed Description

Various functions for controlling and monitoring the status of the DM9161A PHY.

In polled (standalone) systems, the PHY state must be monitored as part of the application. In a threaded (RTOS) system, the PHY state is monitored by the PHY handler thread. The MAC driver will not transmit unless the PHY link is active.

Function Documentation

err_t lpc_phy_init ( struct netif *  netif,
int  rmii 
)

Initialize the DM9161A PHY.

This function initializes the DM9161A PHY. It will block until complete. This function is called as part of the EMAC driver initialization. Configuration of the PHY at startup is controlled by setting up configuration defines in lpc_phy.h.

Parameters:
[in]netifNETIF structure
[in]rmiiIf set, configures the PHY for RMII mode
Returns:
ERR_OK if the setup was successful, otherwise ERR_TIMEOUT

static s32_t lpc_update_phy_sts ( struct netif *  netif,
u32_t  linksts,
u32_t  sdsts 
) [static]

Update PHY status from passed value.

This function updates the current PHY status based on the passed PHY status word. The PHY status indicate if the link is active, the connection speed, and duplex.

Parameters:
[in]netifNETIF structure
[in]linkstsStatus word with link state
[in]sdstsStatus word with speed and duplex states
Returns:
1 if the status has changed, otherwise 0
