READY
Bus Ready (Active Low; Input)
Terminates the bus cycle initiated by ADS.
RESET
Reset (Active High; Input)
Suspends any operation in progress and places the
Am386SX/SXL/SXLV microprocessor in a known reset
state.
SMI (Am386SXLV Only)
System Management Interrupt (Active Low; I/O)
A non-maskable interrupt pin that signals to the
Am386SXLV microprocessor to suspend execution
and enter System Management Mode. SMI has an in-
ternal pull-up resistor. SMI has a dynamic internal
pull-up resistor that is disabled when the processor is
in SMM. SMI is not three-stated during Hold Acknowl-
edge bus cycles.
SMIADS (Am386SXLV Only)
SMI Address Status (Active Low; Output)
When active, this pin indicates that a valid bus cycle
definition and address (W/R, D/C, M/IO, BHE, BLE,
and A23–A1) are being driven at the Am386SXLV mi-
croprocessor pins while in the System Management
mode. Bus cycles initiated by SMIADS must be termi-
nated by SMIRDY.
SMIRDY (Am386SXLV Only)
SMI Ready (Active Low; Input)
This input terminates the current bus cycle to the SMM
mode address space in the same manner the READY
pin does for the normal mode address space. SMIRDY
has an internal pull-up resistor. READY and SMIRDY
must not be tied together.
V
CC
System Power (Input)
Provides the 5 V nominal DC supply input.
V
SS
System Ground (Input)
Provides the 0-V connection from which all inputs and
outputs are measured.
W/R
Write/Read (Output)
A bus cycle definition pin that distinguishes write cycles
from read cycles.
