GENERAL DESCRIPTION
5/55
Issue 1.1
The need for system configuration jumpers is
eliminated by providing address mapping support
for PCMCIA 2.0 / JEIDA 4.1 PC-Card memory
together with address windowing support for I/O
space.
Selectable interrupt steering from PC-Card to
internal system bus is also provided.
The STPC Industrial implements a multi-function
parallel port. The standard PC/AT compatible
logical address assignments for LPT1, LPT2 and
LPT3 are supported.
The parallel port can be configured for any of the
following 3 modes and supports
Standard
1284
parallel
standards as follow:
-Compatibility Mode (Forward channel, standard)
-Nibble Mode (Reverse channel, PC compatible)
-Byte Mode (Reverse channel, PS/2 compatible)
the IEEE
protocol
interface
The STPC Industrial BGA package has 388 balls,
but this is not sufficient for all the integrated
functions, therefore some features are sharing the
same balls and can not be used at the same time.
The STPC Industrial configuration is done by
‘strap options’. It is a set of pull-up or pull-down
resistors on the memory data bus, checked on
reset, which auto-configure the STPC Industrial.
We
can
distinguish
independently configurables
: The ISA / Local
Bus block, the Serial 1 / TFT block, and the PCI /
PC Card block.
From the first block,we can activateeither the ISA
bus and some IPC additionnal features, or the
Local bus, the parallel port and the second serial
interface.
From the second block, we can activate either the
first serial port, or the TFT extension to get from 4
bit per colour to 6 bit per colour.
From the third block, we can activate either the
PCI bus, or the PC Card interface (CardBus/
PCMCIA/ZoomVideo).

The STPC Industrial core is compliant with the

specification to provide a standard method by
which the BIOS can control the power used by
personal computers. The Power Management

consumption providing a comprehensive set of
features that control the power usage and
supports compliance with the United States
Environmental Protection Agency’s Energy Star
Computer Program. The PMU provides following
hardware structures to assist the software in
managing the power consumption by the system.
- System Activity Detection.
- 3 power-down timers detecting system inactivity:
- Doze timer (short durations).
- Stand-by timer (medium durations).
- Suspend timer (long durations).
- House-keeping activity detection.
- House-keeping timer to cope with short bursts of
house-keeping activity while dozing or in stand-by
state.
- Peripheral activity detection.
- Peripheral timer detecting peripheral inactivity
- SUSP# modulation
performance in various power down states of the
system including full power on state.
- Power control outputs to disable power from
different planes of the board.
Lack of system activity for progressively longer
periods of time is detected by the three power
down timers. These timers can generate SMI
interrupts to CPU so that the SMM software can
put the system in decreasing states of power
consumption. Alternatively, system activity in a
power down state can generate SMI interrupt to
allow the software to bring the system back up to
full power on state. The chip-set supports up to
three power down states described above, these
correspond to decreasing levels of power savings.

The
execution of the current instruction, any pending
decoded instructions and associated bus cycles.
During the suspend mode, internal clocks are
stopped.
Removing power down, the processor
resumes instruction fetchingand begins execution
in the instruction stream at the point it had
stopped. Because of the static nature of the core,
no internal data is lost..
