Figure 5-7. Typical Timing for LFRAME#
Figure 5-8. Abort Mechanism
LFRAME# Usage
Start of Cycle
For Memory, I/O, and DMA cycles, the ICH4 asserts LFRAME# for 1 clock at the beginning of the
cycle
Abort Mechanism
When performing an Abort, the ICH4 drives LFRAME# active for four consecutive clocks. On the
fourth clock, it drives LAD[3:0] to 1111b.
The ICH4 performs an abort for the following cases (possible failure cases):
•

LAD[3:0]
LAD[3:0]
ICH4 starts a Memory, I/O, or DMA cycle, but no device drives a valid SYNC after four
consecutive clocks.
ICH4 starts a Memory, I/O, or DMA cycle, and the peripheral drives an invalid SYNC pattern.
A peripheral drives an illegal address when performing bus master cycles.
A peripheral drives an invalid value.
