Status Programming Examples.
Table C-3 shows four examples that set the Questionable Status register group bits to
enable specific conditions. Refer also to Figure C-4.
NOTE
PTR and NTR Filter programming is shown for consistency. In many cases, the default filter values make
programming them unnecessary.

Operation Status Group
Register Functions.
The Operation Status registers record signals that are part of the power supply’s normal operation. As
shown in Figure C-4, the group consists of a set of registers similar to the Questionable Status group. The output of the
Operation Status group is logically-ORed into the OPER(ation) summary bit (7) of the Status Byte register.

Register Programming.
Programming for this group is derived from the
STAT:OPER
commands (Table C-4).
