5.6 Service Requests
When the "S1" mode is set, a service request will be sent
in the event of an overvoltage or overcurrent input, or for
programming errors such as undefined codes or format
errors.
Following transmission of the service request, the
controller sends a serial poll, and the device responds by
transmitting its status byte and resetting the SRQ bit (bit
6).
When "S0" is set, a service request is not sent, but the
status byte is transmitted.
The OVER V or OVER A bit (bit 0 and 1) will be reset
with the serial poll, but a SYNTAX ERROR bit (bit 2)
remains until the next time the device is designated as
the listener, at which time it is reset.
