Event Handling Sequence
In this description, the numbers in parentheses map to the corre-
sponding numbers in Figure 3-6.
When an event occurs, a signal is sent to the DESER (1). If that type
of event is enabled in the DESER (that is, if the bit for that event
type is set to 1), the appropriate bit in the SESR is set to one and the
event is recorded in the Event Queue (2). If the corresponding bit in
the ESER is also enabled (3), then the ESB bit in the SBR is set to
one (4).
When output is sent to the Output Queue, the MAV bit in the SBR is
set to one (5).
When a bit in the SBR is set to one and the corresponding bit in the
SRER is enabled (6), the MSS bit in the SBR is set to one and a
service request (GPIB only) is generated (7).
Figure 3-6 shows how to use the status and event handling system.
