/* Library and Example code for use of the Jefferson Lab
   VME Based 250MHz Flash ADC Module

   Requires: FADC
             vxWorks 5.5 or later
             universeDma or tempeDma Library


   fadcLib.c fadcLib.h   : Library
   fadc_list.crl         : Readout list for 1 ADC
   fadc_daq.boot         : Boot script standalone
   roc4_fadc_coda26.boot : Boot scripte for ROC readout

Basics:

  faInit(addr,addr_inc,num,flag)

    addr: A24 VME address set by micro switches on the FADC

    addr_inc: With multiple boards this is the value
              that the A24 address is incremented between
              base addresses of each board (typically 0x1000)

    num: Number of F1TDCs to initialize

    flag: 16 bit integer
       Low 4 bits - Specifies the default Signal distribution (clock,trigger) 
                    source for the board (INT, FP,P2,VXS)
                   0  CLK (Internal)  TRIG (FP)
                   1  CLK (Internal)  TRIG (Internal)
                   2  CLK (Internal)  TRIG (P2)
                   3  CLK (Internal)  TRIG (VXS)
                   4  CLK (FP)        TRIG (FP)   (VME SDC Mode)
                   5-7  Invalid - default to 4
                   8  CLK (P2)        TRIG (P2)   (VME BDC Mode)
                   9-11 Invalid - default to 8
                  12  CLK (VXS)       TRIG (VXS)  (VXS Mode)
                  13-15 Invalid - default to 12


           High 12bits - A16 Base address of FADC signal dist
                         module (if source = 4 SDC Mode). This board
                         can control up to 5 FADC Boards.


Examples:  

     Initialize a single FADC at address 0xed0000. 
      (Internal Clock, Front Panel Trigger)

        faInit(0xed0000,0,0,0)

---------------------------------------------

     Initialize 5 FADC boards at   0xee0000
                                   0xee1000
                                   0xee2000
                                   0xee3000
                                   0xee4000
                 FADC SDC Board at 0xed00
       Front Panel Trigger and Clock

       faInit(0xee0000,0x1000,5,0xed04)
