Operation event status register set.
To read condition, enable, event, NTR and PTR registers:
operreg = status.operation.condition
operreg = status.operation.enable
operreg = status.operation.event
operreg = status.operation.ntr
operreg = status.operation.ptr
To write to enable, NTR and PTR registers:
status.operation.enable = operreg
status.operation.ntr = operreg
status.operation.ptr = operreg
Set operreg to one of the following values:

0 Clears all bits.

To set CAL bit (B0):
status.operation.CALIBRATING
or
status.operation.CAL

To set MEAS bit (B4):
status.operation.MEASURING
or
status.operation.MEAS

To set PRMPTS bit (B11):
status.operation.PROMPTS
- or -
status.operation.PRMPTS

To set USER bit (B12): status.operation.USER

To set INST bit (B13):
status.operation.INSTRUMENT_SUMMARY
- or -
status.operation.INST

To set PROG bit (B14):
status.operation.PROGRAM_RUNNING
- or -
status.operation.PROG
operreg can also be set to the decimal weight of the bit to be set: To set bit B0 (CAL),
set operreg to 1 (20).
To set bit B4 (MEAS), set operreg to 16 (24).
To set bit B11 (PRMPTS), set operreg to 2048 (211).
To set more than one bit of the register, set operreg to the sum of their decimal
weights. For example, to set bits B0 and B4, set operreg to 17 (1 + 16).
