The LSI53C040 Firmware
2-7
Note:
The user must be aware that this compiler does
not
generate re-entrant code, that function parameters are
not
passed on the stack, and that interrupt level routines and
background routines
cannot
share subroutines. Virtually all
of the source code is written in C. Assembly language is
only needed for stack initialization before control is passed
to the C code.
2.2 The LSI53C040 Firmware
The heart of the LSI53C040 architecture is its 52 input and output pins
(28 MPIO pins and 24 MPLED pins). The user may specify (by using the
configuration utility) an almost unlimited number of configurations. The
SAF-TE firmware was designed to make these configurations simple to
implement by using this utility. Additionally, the SAF-TE firmware is
coupled with a software state machine that polls all of the binary inputs
and drives all of the binary outputs. Simultaneously, the firmware
maintains copies of all the necessary SAF-TE/SCSI command responses
so that the SCSI interrupt software can return these responses to a
host/initiator at any time.
This state machine design allows the user to specify all of the inputs and
outputs without having to change the 8032 firmware. In addition, this
design actually simplifies and shortens the size of the 8032 firmware, by
moving much of the decision making process to the configuration utility.
Consequently, more memory is available in the 8032 for user
enhancements. Refer to
Chapter 5
for more detailed information about
configuration data and the configuration utility.
The program and data for this state machine design is passed from the
configuration utility to the firmware by using a data structure called
config
. In addition, the
config
data structure also contains all the
information gathered by the configuration utility, such as the SCSI ID,
TWS devices to be supported, scanning intervals, etc.
The 8032 microcontroller is at the core of the LSI53C040 device and
runs at 40 MHz. This microcontroller provides more than sufficient
processing power to complete the work to be done by the LSI53C040.
The environmental monitoring protocols, such as SAF-TE and SES, do
