AMD LPC INTERFACE CONTROLLER DRIVER



This active-low signal indicates the beginning of an LPC bus transaction. Driven by the host only. These four bidirectional signals carry multiplexed address, data, and other information.

Like the previous two control signals, these signals have weak pull-up resistors on them, so they will remain in the all-ones state if not actively driven by a device. There are six additional signals defined, which are optional for LPC devices that do AMD LPC Interface Controller require their functionality, but support for the first two is mandatory for the host: This is an output from a device that wants to perform direct memory access, either via the Intel compatible DMA controller, or AMD LPC Interface Controller LPC-specific bus master protocol.

The host must provide one corresponding input pin per device that needs it minimum two. Serialized Intel compatible interrupt signal. Open-collector signal used to restart the clock in systems that AMD LPC Interface Controller stop it for power management. Not required if the host does not stop the clock. May be AMD LPC Interface Controller to the equivalent PCI signal. Open-collector power management event, to wake the system from a sleep state. Optional output from the host to warn the LPC device that power is about to be removed and it should not make any interrupt or DMA requests. System management interrupt request.

In particular, it shares the restriction that two idle cycles are required to "turn around" any bus signal so that a different device is "speaking". In the first, the bus is actively driven high.

In the second, the bus is undriven and held high by the pull-up resistors. A new device may begin sending data over the bus on the third cycle. LPC operations spend a large fraction of their time performing AMD LPC Interface Controller turn-arounds. All bus cycles except the byte firmware read cycle, in which of the clock ticks consumed by this cycle actually are used to transfer data to get a throughput of Intel AMD LPC Interface Controller made it possible to put operating system images and software applications on a single flash memory chip directly connected to the LPC bus, as an alternative to a Parallel ATA port.

This is usually followed by the transfer address field. The size of the address depends on the type of cycle: For system memory access, the address is 32 bits, transferred most-significant nibble first over 8 cycles. ISA-style DMA accesses do not have an address per se, but a two clock cycles transfer a nibble containing the DMA channel number, and a second nibble giving the transfer size.

See the section on DMA below. For a write, the address described above is followed by the data field, 8 bits transferred with the least significant nibble first over two cycles. Following this, the host turns the bus over to the device. This turn-around take two cycles, and operates the same way as the conventional PCI bus control signals: During the second cycle, the host ceases AMD LPC Interface Controller drive the lines, although they remain AMD LPC Interface Controller due to the pull-up resistors. The device may drive the lines beginning with the third cycle.

Following any turn-around to the device is a minimum of one SYNC cycle. The number is variable, under the control of the device to add as many wait states as it needs. The bit patterns and indicate that the sync cycles will continue. The wait AMD LPC Interface Controller when the device drives a pattern of ready or error on the LAD bus for one cycle.

In the case of reads, this is followed by 8 bits of data, transferred least significant nibble first over two cycles, the same as for a write. The device then turns the bus around to the host again taking another two cyclesand the transfer is AMD LPC Interface Controller the host may send the START field of another transfer on the next cycle.

After seeing three cycles of two cycles are allowed, in addition to the two turn-around cycles, for a slow device to decode the address and begin driving SYNC patternsthe host will abort the operation. It also acts as the central DMA controller for devices on that bus if the memory controller is AMD LPC Interface Controller the chipset. ISA-compatible DMA uses an Intel compatible DMA controller on the host, which keeps track of the location and length of the memory buffer, as well as the direction of the transfer. The host then performs a DMA cycle. DMA cycles are named based on the memory access, so a "read" is a transfer from memory to the device, and a "write" is a transfer from the device to memory.
