Examples
*OPC? might return 1 to indicate that all pending OPC operations are finished.
*PSC
Sets and queries the power-on status flag that controls the automatic power-on
states of SRER and ESER. When *PSC is true, the Service Request Enable
Register (SRER) and Event Status Enable Register (ESER) are set to 0 at
power-on. When *PSC is false, the current values in the SRER and ESER
are preserved in nonvolatile memory when power is shut off and are restored
at power-on.

Arguments
<NR1> = 0 sets the power-on status clear flag to false, disables the power-on clear,
and allows the power supply to possibly assert SRQ after power on.
<NR1> ≠ 0 sets the power-on status clear flag to true. Sending *PSC 1 therefore
enables t he power-on status clear and prevents any SRQ assertion after power-on.
