Description
The RQS command sets a bit mask that specifies which service requests
can interrupt a program sequence. Each service request has a
corresponding bit number and decimal equivalent of that bit number, as
shown in Table 7-1 on page 372. Use the decimal equivalents to set the
bit mask. For example, to set a mask for bits 4 and 5, add the decimal
equivalents (16 + 32 = 48), then send the command RQS 48. For more
service request information, refer to Chapter 5.
