The SRQ mask can be set to mask bits O-3 of the
Status Register. To set the mask first determine which
conditions you want to interrupt the controller, for
example sweep started, sweep stopped and so on.
Determine the decimal number (1-16) corresponding to
those conditions. A "1" in the mask byte enables the
corresponding interrupt condition. Then output the
"MS" instruction mnemonic followed by the appropriate
character (as shown in Table 10-2).
