Reading registers
Any register in the status structure can be read by using the appropriate query (?)
command. The following explains how to interpret the returned value (response
message). The actual query commands are covered later in this section. (See
Table 15-3 and Table 15-4 through Table 15-7.)
The response message will be a value that indicates which bits in the register are
set. That value (if not already binary) will have to be converted to its binary equiv-
alent. For example, for a binary value of 100101, bits B5, B2, and B0 are set.
The returned value can be in the binary, decimal, hexadecimal, or octal format.
The
FORMat:SREGister command is used to select the data format for the returned
value (Table 15-2).
For non-decimal formats, one of the following headers will accompany the
returned value to indicate which format is selected:
#B = Header for binary values
#H = Header for hexadecimal values
#Q = Header for octal values
Valid characters for the non-decimal parameter values are shown as follows:
