o Error Code is encoded into 1411 UShort_t array


[Tracklet level]-------------------------

UShort_t[1] = 0000 : 0000 : 0000 : 00em

  m: max number of trackles > 256
  e: number of tracklet end marker words < 2 



[HC level]------------------------

UShort_t[2] = 0000 : 000i : hgfe : dcba

  a: H0 header mask has an error
  b: H0 header insane
  c: H1 header mask has an error
  d: No data (including HC header) in the buffer 
  e: No data right after HC header in the buffer (code:2)
  f: More MCM data than expected
  g: Buffer ends in the middle of data
  h: END_OF_TRACKLET_MARKERNEW appeared in HC data
  i: HC data corrupted (can see more detail in the MCM, ADC level error codes) 



[MCM level]------------------------
   
UShort_t[idx] = 00ii : ihhh : hgfe : dcba (2 < idx < 2+64, where idx is sequential mcm order)

  a: Wrong MCM header mask
  b: MCM and ROB number from MCM header is different from expected
  c: Event number of current MCM is different from that of reference MCM(1st
    read mcm of given SM)
  d: Event number of current MCM is from past?
  e: Wrong ADC Mask word
  f: ADC counts(number from bit indicating total number and number from bit
    masks) from ADCMask are different
  g: ADC data corrupted (can see more detail in the ADC level error codes)
  h: MCM number
  i: ROB number 



[ADC level]------------------------

UShort_t[idx] = dddc : cccb : bbbb : aaaa 
       (where idx = 66 + 21*(mcmNumber + 16*int(robNumber/2)) + adcNumber)

  a: number of ADC words having wrong ADC data mask 
  b: adc number
  c: mcm number
  d: rob number
