Terminology
A “#” symbol after a signal name refers to an active low signal, indicating a signal is in the active
state when driven to a low level. For example, when RESET# is low, a reset has been requested.
Conversely, when NMI is high, a nonmaskable interrupt has occurred. In the case of signals where
the name does not imply an active state but describes part of a binary sequence (such as address or
data), the “#” symbol implies that the signal is inverted. For example, D[3:0] = “HLHL” refers to a
hex ‘A’, and D[3:0]# = “LHLH” also refers to a hex “A” (H= High logic level, L= Low logic level).

“System Bus” refers to the interface between the processor and system core logic (a.k.a. the chipset
components). The system bus is a multiprocessing interface to processors, memory, and I/O.
