3.8 Status reporting
The ITC5xx provides four 8 bit registers ESR, STB, ESE and SRE and three 16 bit
registers DEC, DEE and EDE to program various service request functions and
status reporting.
(Please refer to the IEEE488.2-1992 standard chapter 11)
3.8.1 Standard event status register (ESR)
The bits of this register mirror the following standard events:
Power on
This event bit indicates, that an off to on transition has
occurred in the power supply. So it is high after switching
on the device for the first time.
