Note: When either status register is read, status conditions in
that register are reset. In the case of voltage priority
indications, if two or more voltages were out of limits, then
another indication would automatically be generated if it was
not handled during interrupt service. Errant voltages may be
disabled in the control register until the operator has time to
clear the errant condition or set the limit higher or lower.
