4. Theory of Operation

4-42

The computer board contains a CPU, memory, system software stored in EPROM, and
two (2) Field Programmable Gate Arrays (FPGA’s) containing logic for display control, 8
channel 10 bit ADC, valve control, pump motor control, keyboard scan, fault monitoring,
watchdog, and serial interface.

The CPU

is a 16 bit microcontroller. This device contains a number of on board

peripherals that are utilized as follows:

The 8 channel 10 bit ADC

measures: input thermopile voltage, output

thermopile voltage, input and output ambient temperatures, pressure, 30V supply
voltage, diversion valve current, and thermopile reference.

2 pulse width modulators: valve energy and spare.

7 hardware interrupts: power module, display, valve positions (open, middle,
close), door position, and spare.

4 input capture timers: only two (2) are used for fluid out detector and air
detector.

5 output timers: only one (1) is used: sound beep

1 RS232 logic port

1 serial interface port: communicate with power module

7 programmable chip selects: EPROM, Real Time Clock (RTC), RAM word, RAM
lower byte, RAM upper byte, display FPGA, and motor FPGA.

The board contains three types of memory, EPROM, RAM and battery backed up
RAM.    The  EPROM  is  used  to  boot  the  system  on  power  up,  and  to  store  the
main  program  when the power  is  off.   The  system  RAM  is  used for  running  the
program  and  temporary  constant  storage.  The  battery  backup  RAM  is  used  for
storing  calibration  constants  that  are  generated  during  the  system  calibration.
The  battery  backed  up  memory  also  contains  a  real  time  clock  and  watchdog.
These  constants  are  compared  with  the  ones  stored  on  the  power  module  to
ensure  calibration  accuracy.    If  the  daughter  board  is  disconnected  from  the
computer board, or if either of the temperature probe assemblies is removed, the
memory  will  be  erased,  thereby  forcing  re-calibration.  This  is  a  safety  feature,
since  remove  the  daughter  board  or  the  temperatures  probes,  resulting  in
alignment  change.  A  jumper  can  be  installed  to  bypass  this  function  during
calibration and troubleshooting.

The display FPGA performs two (2) main functions. The first function is the
interfacing of the computer to the display through an independent memory. The
second function is to provide a locking method for the battery backed up RAM so
that it cannot be modified accidentally.
