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. After you have properly handled an interrupt, you will need to write a 1 back to the appropriate bit in CSR0 or CSR4 before sending EOI to you interrupt controller or the interrupt will continue to be signalled. And you may want to set bit 11 of CSR4 which automatically pads Ethernet packets which are too short to be at least 64 bytes. During normal initialization and use of the cards, the CSRs are used exclusively. Thank You for Submitting a Reply,! You can do this by either waiting for an interrupt if you didn’t disable the initialization done interrupt in CSR3 or by polling until CSR0 bit 8 is set. Once reported, our staff will be notified and the comment will be reviewed.

You need to parse ACPI tables etc.
Once all the control registers are set up, you set bit 0 of CSR0, and then wait for initialization to be done. Your message has been reported and will be reviewed by our staff.
A further important register exists in the IO space called the reset register. You also need a simple way of incrementing the pointer and wrapping back to the start if necessary.

You probably want to set it to zero enable transmit and receive functionality, receive broadcast packets and those sent this physical address, disable promiscuous mode. Since you’ve already submitted a review for this product, this submission will be added as an update to your original review. Advertisements or commercial links.
The card regularly scans all the transmit ethhernet looking for one it hasn’t sent, and then will transmit those it finds.
You can do this by either waiting for an interrupt if you didn’t disable the initialization done interrupt in CSR3 or by polling until CSR0 bit 8 is set. Views Read View source View history.
Sending packets involves simply writing the packet details to the next ethernwt transmit buffer, then flipping the ownership for the particular ring buffer entry to the card. We simply fail and return. After you have properly handled an interrupt, you will need to write a 1 back to the appropriate bit in CSR0 or CSR4 before sending EOI to you interrupt controller or the interrupt will continue to be signalled.

Note that if you want to wait for an interrupt you will also need to set bit 6 of CSR0 or interrupts won’t be generated you will need to enable this anyway to get notification of received packets, so it makes sense to set it at the same time as the initialization bit.
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.
Promote cracked software, or other illegal content. The next section will enable some interrupts on the card. Thank You for Submitting Your Review,! If a new packet has been signalled then CSR0 bit 10 will be set. Given that the MMIO access is sometimes absent on emulators or certain systems, this article will focus on the IO port access. There are two ways of setting up the card registers: Login or create an account to post a review.

Pcet are other bits in CSR0 than can be set depending on how you set up interrupt masks in CSR3 and additionally other bits in CSR4 that can signal interrupts although these are usually masked out on reset. You are logged in as. The card uses two ring buffers to store packets:
