  header 6464 32 0 telemetry Header Telemetry Packet Header
    synch 3232 32 0 uint32 = 0x736f4166 This field delimits the start of a telemetry packet.
    telemetryLength 1010 1 32 uint10 = 6+n/2 This field indicates the total number of 32-bit words in the telemetry packet
    formatTag 66 1 42 uint6 = 3 This field identifies the content of the telemetry packet [see enum TlmFormatTag]: TTAG_READ_SRAM
    sequenceNumber 1616 1 48 uint16 This field is the sequence number of the telemetry packet
  commandId 1616 16 64 uint16 Command Identifier of command which initiated the read
  ccdId 44 1 80 uint4 CCD Controller whose SRAM is being read
  bepTickCounter 3232 32 96 uint32 Back End Timer Tick interrupt counter value at start of read (1/10 sec. ticks)
  requestedIndex 1616 16 128 uint16 This is the original index requested by the Read Sram command
  requestedWordCount 1616 16 144 uint16 This is the original word count requested by the Read Sram command
