 CAMAC Commands
 ~~~~~~~~~~~~~~

 N F(O) A(O) :  Reads MASK                   (R1-R16).
 N F(O) A(1) :  Reads internal DATA LATCH    (R1-R16).
 N F(1) A(O) :  Reads internal DAC THRESHOLD (R1-R1O).
 N F(1) A(1) :  Reads current threshold level and status (R1-R1O, R14-R16) :
      R1-R1O :  ADC reading, -1 mV/bit conversion gain
         R14 :  State of the SYNC input at the time the N F(1) A(1) command executes,
                1 = No SYNC present, 0 = SYNC is present.
         R15 :  1 = Time-Over-Threshold mode in effect, 0 = UPDATE mode is in effect.
         R16 :  1 = LOCAL mode is in effect, 0 = REMOTE mode is in effect.

 N F(16) A(O):  Write MASK       (W1-W16).   0 = Mask Off,   1 = Mask On.
 N F(17) A(0):  Write THRESHOLD  (W1-W10).   0 = -10 mV,   3FF = -1.033 V.
 N F(17) A(1):  Starts a Threshold ADC cycle, always returns Q=X=1.
                The ADC cycle lasts 60uSEC max.
                Note that Read Threshold command also starts a new conversion at S2 time.

 N F(24) A(O) at S1 : Set to LOCAL mode.
 N F(25) A(O) at S1 : Generates a test input to all not MASKED channels.
 N F(26) A(O) at S1 : Set to REMOTE mode.
 N F(27) A(O) at S1 : Checks LOCAL/REMOTE mode. Returns Q=1 only if in Remote mode.

 Z at S2 :  The internal mode bit is cleared (Sets LOCAL/REMOTE to LOCAL).
            The MASK register is loaded with all ones.
            The Threshold DAC is set to -1.033 volts.
