Status and Events

Figure 3-6: Status and Event Handling Process

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 is

generated (7).
