If *PSC was set to 0 prior to power-down, then at power-on, the enable
registers are loaded from non-volatile memory. Therefore, any values that you
have stored (
SYSTem:NVSave command) are returned to the registers.
However, if *PSC was set to 1, then at power-on the factory defaults are
returned.
