Operation event register
The used bits of the operation event register (Figure 13-5) are described as follows:
• Bit B0, Calibrating (Cal): Set bit indicates that the Model 6482 is calibrating.
• Bits B1 through B4: Not used.
• Bit B5, Waiting for Trigger Event (Trig): Set bit indicates that the Model 6482 is in the
trigger layer waiting for a TLINK trigger event to occur.
• Bit B6, Waiting for Arm Event (Arm): Set bit indicates that the Model 6482 is in the arm
layer waiting for an arm event to occur.
• Bits B7 through B9: Not used.
• Bit B10, Idle State (Idle): Set bit indicates the Model 6482 is in the idle state.
• Bits B11 through B15: Not used.
