Fields:

      Attribute(s):  

      Brief:  "Current heater command and LTC control mode"

      Instance(s):  htrCmd

      For the heater bits, a value of '0' indicates that LTC is commanding the heater off. A value of '1' indicates that LTC is commanding the heater on. These heater commands are applied only when LTC is in active control mode.

      Attribute(s):  

      Brief:  "Control mode for VCHP heaters."

      Instance(s):  actvHp

      A bit value of '0' indicates that the heater is under manual, user control. A bit value of '1' indicates that the heater is under automatic, algorithm control.

      Attribute(s):  

      Brief:  "Current heater state and LTC run mode"

      Instance(s):  htrReg

      For the heater bits, a value of '0' indicates that the heater is currently off. A value of '1' indicates that the heater is currently on.

      Attribute(s):  

      Brief:  "Sensor Status and ADC Counts"

      Instance(s):  rawAdc

      Attribute(s):  

      Brief:  "Selected RSVR and RIT sensors"

      Instance(s):  snsrSel

      Attribute(s):  

      Brief:  "Heat pipe RIT and reservoir sensors status"

      Instance(s):  snsrStatus

      Attribute(s):  

      Brief:  "Temperature converted to celsius."

      Instance(s):  dbDelta, resHi, resLo, ritHi, ritLo, temps

      Fixed point scaled by 8 bits (256).
