Line: 1 to 1

HOW TO TELL1 board [information for the calo piquet]

Line: 167 to 167
  • Once done, the FSM state switches back to NOT READY.
  • Do Configure the given tell1 board to check that everything is ok.

Spy Memories:


Spy Memories

  The CALO tell1 firmware contains spy memories in the PP-FPGA [size: 256 words - 1 CROC event: 34 words (1 header - 1 ctrl word and 32 data words)] on the ORx outputs which allow to read what was received by the CROC before any treatment of the data.
Line: 209 to 209
