4.3 STETHER_Config ()

Prototype:

void STETHER_Config (U32 Eth_BaseAddr,U8 Addr_Shift,U8 Tsc_Interrupt,U8 Int_Level,

U8 Use16Bit,U8 Trans_Len)

Description:

This routine configures the 78Q8430 interface. It records the input parameters in globally available

variables for use by the driver.

Parameters:

Eth_BaseAddr 78Q8430 base address

Addr_Shift address shift

Tsc_Interrupt tsc interrupt

Int_Level interrupt level

Use16Bit use 16-bit bus width

Trans_Len transfer packet length

Returns:

none

4.4 STETHER_Config_ARC ()

Prototype:

void STETHER_Config_ARC(NGifnet *netp)

Description:

This function configures the ARC table with the contents of the preset arc_entry[] array found in

DEVICE_CONTROL_STRUCT. The ARC address has the same format as a standard 6 byte MAC
