To actually set up the card registers, we provide it with the address of our initialization structure by writing the low bits of its address to CSR1 and the high bits to CSR2. MODE provides various functions to control how the card works with regards to sending and receiving packets, and running loopback tests.

This article will focus on the Am79CA a. You should also have a variable that stores the current ‘pointer’ into each buffer i.

Interrupt done mask – if set then you won’t get an interrupt when the card has finished initializing. Transmit interrupt mask – if set then an interrupt won’t be triggered when a packet has completed sending.

You also need to specify the physical address MAC address you want the card to use. You can do this by either waiting for an etherent if you didn’t disable the initialization done interrupt in CSR3 or by polling until CSR0 bit 8 is set. Personal tools Log in.
