Counter1
This is the Utility Counter 1 control field. There are 4 modes:
• ‘Load’ - Load the utility counter with the contents of the Operand
field. The operand field must be a hexadecimal number. The ‘L’ key
pressed in this field sets the ‘Load’ mode.
• ‘Hold’ - Hold the counter at its current value. The ‘H’ key pressed
in this field sets the ‘Hold’ mode.
• ‘Up’ - Increment the counter by one. The ‘U’ key pressed in this
field sets the ‘Up’ mode.
• ‘Down’ - Decrement the counter by one. The ‘D’ key pressed in this
field sets the ‘Down’ mode.
This is used by the EPPutInstructionData functional call.
Counter2
This is the Utility Counter 2 control field. The modes and key input is the
same as the Counter 1 field. This is used by the EPPutInstructionData
functional call.
Operand
This is used for the JUMP opcodes or the load values for the utility counters. If
a JUMP instruction is used, this field must be a non-empty valid label defined
in the Label field. If a ‘Load’ in either or both utility counters is used then this
field is formatted as a hexadecimal number. This field is used by the
EPPutInstructionData functional call.
Timing Set
This is the timing set to be used for the vector. To prevent errors, the timing set
must exist in the Timing Editor. This field is used by the
EPPutTimingSelectData functional call.
Fail
Enable fail checking for this step. For the current step, a ‘F’ typed into this
field enables fail checking whereas a ‘X’ typed into this field disables fail
checking. This field is used by the EPPutInstructionData functional call.
Acc0 to AccX
The AccX fields control the accumulators of the EPIO board. Each board
contains 4 AccX fields. For the current step, a ‘L’ typed into this field loads the
