System Management Interrupt
invokes System Manage-
ment Mode (SMM). SMI# is the highest priority interrupt. It is
latched on its falling edge and it forces the CPU into SMM
upon completion of the current instruction. SMI# is recognized
on an instruction boundary and at each iteration for repeat
string instructions. SMI# cannot interrupt LOCKed bus cycles
or a currently executing SMM. If the processor receives a sec-
ond SMI# while it is in SMM, it will latch the second SMI# on
the SMI# falling edge. However, the processor must exit SMM
by executing a Resume instruction (RSM) before it can ser-
vice the second SMI#.
System Management Interrupt Active
indicates that the
processor is operating in System Management Mode (SMM).
It is asserted when the processor initiates an SMM sequence
and remains asserted (low) until the processor executes the
Resume instruction (RSM).
Write/Read
indicates whether the current bus cycle is a write
cycle or a read cycle. When W/R# is high, the bus cycle is a
write cycle; when W/R# is low, it is a read cycle.
System Power
provides the nominal DC supply input.
