OPERation Status Register 
The operation status register is a standard SCPI, 16-bit register which 
contains information about conditions which are part of the power 
supply's normal operation. The Operation Status data structure has the 
operation status register and two sub-registers to represent shutdown 
and protection shutdown. Each of the sub-registers is summarized in a 
summary bit. 
Figure 5-22 represents the Operation Status data structure. The “+” 
represents the logical summation/or of bits in a register. Table 5-11, 
Table 5-12, and Table 5-13 describe the meanings of each bit as well as 
the bit number and bit weight.
