1. Initialize your TTC system (should be sending BC0s but no L1A's)
2. Using the Python program amc13_control.py:
   1. enable AMC Inputs: "I [list of AMC inputs to be enabled]" i.e. "I 0,1" for lowest two inputs.
   2. Switch to Virtex chip: "t1"
   3. Enable fake data: "w 1 0x83"
      1. bit 0 - Run mode
      2. bit 1 - DAQ Link enable
      3. bit 7 - Fake data mode (no AMCs required)
   4. Reset virtex chip "w 0 1"
3. On your TTC system: Send Event Counter Reset (optional)
4. On your TTC system: Send L1A
5. Again, using anc13_control.py:
   1. Display status "s"
   2. Dump event data to a binary file: "d test.dat"

The status after receiving one or more L1A should look something like this:

*****AMC13 status*****

Control 0: 03000041
   DAQ Link Down
   TTC BCNT Error

Control 1: 00100081
   Crate fake event at L1A

AMC Link status: 00000001
  AMC Enabled List: 00
  --No AMC links enabled--

TTC Info:
                 EvN: 00000002
                 BcN: 00000880

EVB 32-bit Counters:

      SDRAM Event Ct: 00000390
   Unread SDRAM Evts: 00000001

If you write a data file with the D command, you can dump it as follows (HCAL data format, sorry!):

$ od -Ax -t x8 test.dat
