8.11.2. Service Request: Enable and Event Registers
The conditional Registers are continuously monitored. When a change is detected in a
register bit, which is enabled, the power supply will generate an SRQ message.
The SRQ message is: "Inn" terminated by CR, where the nn is the power supply address.
The SRQ will be generated either in Local or Remote mode.
Refer to Tables 8-10 to 8-13 for details of the Enable and Event registers.
