description (continued)
The SMJ320C3x internal busing and special digital-signal-processing instruction set have the speed and
flexibility to execute up to 60 MFLOPS. The SMJ320C3x optimizes speed by implementing functions in
hardware that other processors implement through software or microcode. This hardware-intensive approach
provides performance previously unavailable on a single chip.
The SMJ320C3x can perform parallel multiply and ALU operations on integer or floating-point data in a single
cycle. Each processor also possesses a general-purpose register file, a program cache, dedicated ARAUs,
internal dual-access memories, one DMA channel supporting concurrent I/O, and a short machine-cycle time.
High performance and ease of use are results of these features.
General-purpose applications are greatly enhanced by the large address space, multiprocessor interface,
internally and externally generated wait states, one external interface port, two timers, one serial port, and
multiple-interrupt structure. The SMJ320C3x supports a wide variety of system applications from host processor
to dedicated coprocessor.
High-level-language support is easily implemented through a register-based architecture, large address space,
powerful addressing modes, flexible instruction set, and well-supported floating-point arithmetic.
For additional information when designing for cold temperature operation, please see Texas Instruments
application report 320C3x, 320C4x and 320MCM42x Power-up Sensitivity at Cold Temperature, literature
number SGUA001.

XF0 is always set high at the beginning of the execute phase of the interlock-store instruction. When no pipeline conflicts occur, the address of
the store is also driven at the beginning of the execute phase of the interlock-store instruction. However, if a pipeline conflict prevents the store
from executing, the address of the store will not be driven until the store can execute.

reset timing
RESET is an asynchronous input that can be asserted at any time during a clock cycle. If the specified timings
are met, the exact sequence shown in Figure 23 occurs; otherwise, an additional delay of one clock cycle is
possible.
The asynchronous reset signals include XF0/1, CLKX0, DX0, FSX0, CLKR0, DR0, FSR0, and TCLK0/1.
Resetting the device initializes the primary- and expansion-bus control registers to seven software wait states
and therefore results in slow external accesses until these registers are initialized.
HOLD is an asynchronous input and can be asserted during reset.

B. RESET is an asynchronous input and can be asserted at any point during a clock cycle. If the specified timings are met, the exact
sequence shown occurs; otherwise, an additional delay of one clock cycle is possible.
C. In microprocessor mode, the reset vector is fetched twice, with seven software wait states each time. In microcomputer mode, the
reset vector is fetched twice, with no software wait states.
D. Control signals include STRB.
E. The R/W outputs are placed in a high-impedance state during reset and can be provided with a resistive pullup, nominally
18−22 kΩ, if undesirable spurious writes are caused when these outputs go low.

The interrupt (INT) pins are asynchronous inputs that can be asserted at any time during a clock cycle. The
SMJ320C3x interrupts are level-sensitive, not edge-sensitive. Interrupts are detected on the falling edge of H1.
Therefore, interrupts must be set up and held to the falling edge of H1 for proper detection. The CPU and DMA
respond to detected interrupts on instruction-fetch boundaries only.
For the processor to recognize only one interrupt on a given input, an interrupt pulse must be set up and held
to:
D
D
A minimum of one H1 falling edge
No more than two H1 falling edges
The SMJ320C3x can accept an interrupt from the same source every two H1 clock cycles.
If the specified timings are met, the exact sequence shown in Figure 24 occurs; otherwise, an additional delay
of one clock cycle is possible.

HOLD timing
HOLD is an asynchronous input that can be asserted at any time during a clock cycle. If the specified timings
are met, the exact sequence shown in Figure 27 occurs; otherwise, an additional delay of one clock cycle is
possible.
The NOHOLD bit of the primary-bus control register overrides the HOLD signal. When this bit is set, the device
comes out of hold and prevents future hold cycles.
Asserting HOLD prevents the processor from accessing the primary bus. Program execution continues until a
read from or a write to the primary bus is requested. In certain circumstances, the first write is pending, thus
allowing the processor to continue until a second write is encountered.

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
